How do fuel cell electric vehicles work using hydrogen?
- Hydrogen gas enters the fuel cell through the anode. In the anode, the atoms of hydrogen create a chemical reaction with a catalyst, splitting into protons and electrons. ...
- There is a porous electrolyte membrane between anode and cathode. The protons pass through it. ...
- In the cathode, the oxygen and protons then combine to produce water.
What is the efficiency of hydrogen fuel cell?
The hydrogen fuel cell requires 2-3 times more energy to drive the same distance, as the overall Well-to-Wheel efficiency is from 25-35%. "In the case of the hydrogen-powered e-car, the losses are much greater: 45 percent of the energy is already lost during the production of hydrogen through electrolysis.
Do fuel cells last forever?
When it comes to longevity, think of a hydrogen-powered car in the same way you would a conventional petrol or diesel car. As such, the fuel cell stack in a Toyota Mirai is engineered to last for the lifetime of the car, boasting the same quality, durability and reliability as any other Toyota.
Do fuel cells wear out?
Fuel cells wear out crazy fast and are hard to regenerate. Hydrogen as a fuel is incredibly hard to make and distribute with acceptably low losses.
How many miles can a fuel cell last?

Why hydrogen is not the future?
Sure, hydrogen is the most abundant element in the universe, and it's only used as an energy carrier, so it doesn't get used up in a fuel cell. However, it doesn't exactly grow on trees either, and there are no underground “hydrogen pockets” that we can simply pump it out from.
How much hydrogen does it take to fill a Toyota Mirai?
Some cars are expensive to purchase, while others are expensive to own. It could cost a fair amount to fill up a Toyota Mirai; the average cost of hydrogen fuel is $16 per kilogram. Since the Mirai holds an average of 5 kilograms, you would be paying around $80.

Is hydrogen fuel cheaper than gasoline?
In 2021, hydrogen retailed $8.50/kg to $10.80/kg higher than gasoline prices matching the same fuel cost per mile for hybrids or conventional gasoline vehicles respectively. Hydrogen has been used commercially for over 80 years, so it is well developed.
Why are hydrogen cars not popular?
The vast majority of car companies have turned away from hydrogen because of the high density of energy consumed in its production, as well as poor funding and backing from governments, which is stopping the hydrogen revolution from expanding ever more.
How long will a Toyota Mirai last?
As such, the fuel cell stack in a Toyota Mirai is engineered to last for the lifetime of the car, boasting the same quality, durability and reliability as any other Toyota.
Do fuel cells have a future?
Fuel cells for commercial vehicles and machines have the potential to become essential for the future of transportation and infrastructure, where we strive to accelerate the development, production, and commercialization of hydrogen fuel cell solutions.
What is the problem with hydrogen fuel cells?
Overall Cost The cost for a unit of power from hydrogen fuel cells is currently greater than other energy sources, including solar panels. This may change as technology advances, but currently this cost is a barrier to widespread use of hydrogen even though it is more efficient once produced.
Why don't we use fuel cells?
Why aren't we all driving them? There's virtually no pure hydrogen on Earth because it's so reactive. Most hydrogen is made from methane [natural gas] in a process that produces carbon dioxide and other greenhouse gases. Hydrogen can also be made from water using electrolysis, but that requires electrical energy.
What is the most common catalyst used to make fuel cells?
Currently, platinum is the most common catalyst used to create fuel cells. While it is effective the high price point has made commercialisation a problem. Instead of using pure platinum, many commercial catalysts are made by coating carbon by tiny platinum nanoparticles. This is efficient in the short term but significantly reduces the overall lifespan of fuel cells.
Is graphene a fuel cell?
New research from Queen Mary University of London suggests that when manufactured in a certain way, graphene could be an effective support material for hydrogen fuel cells. The study was published in the journal Nanoscale, with scientists using an innovative technique to develop graphene-based hydrogen fuel cell catalysts. Durable, scalable and cost effective, the team say the technique could emerge as a commercially available solution for hydrogen fuel cell production.
How long do fuel cells last in Mirai?
automotive fuel cells are rated only for 5000 hours of use, about half of what I consider acceptable.
How long should a car's usage life be?
There are two things you need to be interested in: calendar life (which should ideally be 20 years) and usage life (which should ideally be 1 year). A car has about 5% usage time, the rest of the time it spends idle. The calendar life can't be tested because automotive fuel cells are a relatively new kind of technology.
Why can't we test calendar life?
The calendar life can't be tested because automotive fuel cells are a relatively new kind of technology. However, I would trust more on the calendar life of fuel cells than on the calendar life of batteries of electric vehicles. There should be no continuously occurring chemical reactions in an automotive fuel cell.
How long do H2 fuel cells last?
H2 fuel cells currently in production have a life expectancy of from 5,000 to 10,000 hours. If we apply that to an average driving speed of 45 mph (a combination of in-town on highway driving), we should expect to get 225,000 to 450,000 miles.

Range: A draw. Both fuel cell and battery electric cars have a range of about 350 miles.
How much higher efficiency is a fuel cell than a ICE?
Fuel cell vehicles operate at much higher efficiency levels than ICEs (approximately 3X). That means the value of Hydrogen and gasoline are equivalent when the price per kg of H2 is about 3 times the price per gallon of gasoline.
What is hydrogen fuel cell?
A hydrogen powered fuel cell car basically is a battery electric car, which has a fuel cell which serves as generator for the battery. So a fuel cell car is some sort of a hybrid car. It is rather easy to make a fuel cell plugin hybrid car - just make the battery bigger and install a charging plug.
Is hydrogen storage dangerous?
The biggest misconception is hydrogen volatility/inflammability. Yes, extremely explosive, but nowhere near as dangerous as gasoline which is heavier than air and has a high vapor pressure. If there's an ignition source, gasoline will find it. If there are passengers, gasoline will find them. Hydrogen is much lighter than air and rapidly dissipates.
Is hydrogen gas faster than petrol?
If you compare a hydrogen tank with a big, Tesla style battery, a hydrogen powered car is faster to refill. Right now, hydrogen gas stations are very rare, but filling up a hydrogen tank does not take much more time than filling up a petrol tank.
Do you have to go to a hydrogen station to fill an electric car?
Convenience: Clear win for electric cars. You leave with the car “full" every day from an overnight charge. You don't have to go out of your way to a filling station. With only 1 hydrogen station in some states, you may be going a long way to find the fueling station!
What would happen if a fuel cell was generating hydrogen?
If the fuel cell itself was generating hydrogen from H2O, the system as a whole would generate no net energy--all of the energy obtained from the hydrogen reaction at the end would need to go back into separating the H2O in the first place.
Which aspect of PEM reduces the lifetime of fuel cells?
Poisoning of the catalyst, e.g. by C O, is only one aspect that reduces the lifetime of PEM fuel cells.
What is the new electrocatalyst for hydrogen fuel cells?
The new electrocatalyst for hydrogen fuel cells consists of a thin platinum-cobalt alloy network and, unlike the catalysts commonly used today, does not require a carbon carrier. Credit: Gustav Sievers
How does a catalyst improve fuel cell production?
The new catalyst improves fuel cells significantly, by making it possible to produce more horsepower per gram of platinum. This in turn, makes the production of hydrogen fuel cell vehicles more sustainable.
Why are hydrogen vehicles rare?
Hydrogen vehicles are a rare sight. This is partly because they rely on a large amount of platinum to serve as a catalyst in their fuel cells— about 50 grams. Typically, vehicles only need about five grams of this rare and precious material.
Why is sustainable technology challenging?
Sustainable technologies are often challenged by the limited availability of the rare materials that make them possible , which in turn, limits scalability. Due to this current limitation, it is impossible to simply replace the world's vehicles with hydrogen models overnight. As such, the new technology a game-changer.
Is the new catalyst more stable than the catalysts deployed in today's hydrogen powered vehicles?
At the same time, the new catalyst is much more stable than the catalysts deployed in today's hydrogen powered vehicles, " explains Professor Matthias Arenz from the Department of Chemistry.
How long do your fuel cells last?
The average fuel cell has a life expectancy of between 7-15 years. The overwhelming majority of our fuel cells last between 12-15 years of continuous use depending on fuel used, storage conditions, ventilation, heat and UV exposure, and fitment inside the can and vehicle. For customers in climates with high humidity we highly recommend storage in a cool and dry environment if possible, extra drain and vent holes in the can/bulkhead, and draining of the fuel before storage of the vehicle for more than 30 days. While these steps may seem excessive they will add years to the life of the fuel cell in highly humid environments.
How long does it take to make a fuel cell?
Things like tunnels, tubes, asymmetry of design, nipples, and complexity all add time to the production process and can take anywhere from a few extra hours to days to properly mimic, reduce, and produce. The typical fuel cell takes between 20-25 hours to produce, with some smaller or simpler designs taking less and more complex designs taking longer. Additionally, internal fuel systems or custom designed parts can increase the production time as parts may need to be shipped in or out to vendors for finish or customization. On standard design fuel cells, like our Box End or Sloped Bottom fuel cells the production time is between 2-10 days on parts not already in stock (customization of design or internal parts may increase this time). For a custom fuel cell production time is between 3-5 weeks depending on the design, quantity, parts list, and how extensive any customization of parts may be. While we maintain the largest inventory of plate sizes and designs, performance fuel pumps and filters, and vent/check valve sizes we too get delayed by vendors and ask that our customers be patient when placing a custom order.
What kind of maintenance should I do on the fuel cell?
Maintenance usually includes new gaskets, bolts, washers, cleaning and inspection, and any slight repairs or adjustments that may need to be made to the fuel cell. Still, we build all our fuel cells to our strictest off-road specifications, meaning little to no maintenance is required during the life of the fuel cell. For customers running in dirty or off-road environments we recommend removing the fuel cell bladder from the can for periodic inspection and cleaning of the inside of the can; for track and road applications we recommend inspection of the fuel cell compartment to check for proper ventilation and removal of any excess spillage or fluids that may have built up during normal use. These tasks should be done every 6-12 months depending on use. The foam, fuel lines, vents, pickups, anti-spills, and other hardware are expected to last the life of the cell, so replacement is not recommended unless there is a noticeable problem with leakage or performance. Gaskets can be replaced in intervals of every 2 years but is not necessary unless it is damaged or the plate is being removed regularly for cleaning/inspection.
How often should I replace a fuel cell?
These tasks should be done every 6-12 months depending on use. The foam, fuel lines, vents, pickups, anti-spills, and other hardware are expected to last the life of the cell, so replacement is not recommended unless there is a noticeable problem with leakage or performance.
How often should I replace the fuel hose in my fuel cell?
Hands down one of the top two questions we get, this is a problem that has plagued our competition's customers for years. Simply put, you should never have to replace the fuel hose in a Harmon Racing Cell fuel cell. All the hose we use internally is designed for use with gasoline, so there is no need to replace as the hose will not deteriorate before the rest of the fuel cell. Because the line we use has a lower hardness rating than the fuel cell itself it may become necessary to replace the hose on occasion when normal use has caused the hose to rub against the bladder and through the hose core, causing a hole in the line.
What is a hydrogen fuel cell car?
Hydrogen fuel cell cars are powered by an electric motor and are therefore classified as e-cars. The common abbreviation is FCEV, short for “Fuel Cell Electric Vehicle,” in contrast to a BEV or “Battery Electric Vehicle.”
How environmentally friendly and sustainable is hydrogen fuel cell technology?
A car that uses only renewable energy and produces no harmful emissions would be ideal from an environmental point of view. Let’s take a look at how close fuel cell cars are to this goal in comparison to other types of propulsion:
What is the difference between hydrogen fuel cell and other electric vehicles?
There is one crucial difference between hydrogen fuel cell cars and other electric vehicles – hydrogen cars produce the electricity themselves. So, unlike in fully electric or plug-in hybrid vehicles, the vehicle doesn’t get its power from a built-in battery that can be charged from an external power source (➜ Read more: Electric cars and plug-in hybrids explained ). Instead, hydrogen cars effectively have their own efficient power plant on board: the fuel cell.
How does hydrogen energy work in a car?
Instead, hydrogen cars effectively have their own efficient power plant on board: the fuel cell. In the fuel cell of an FCEV, hydrogen and oxygen generate electrical energy. This energy is directed into the electric motor and/or the battery, as needed.
Why are operating costs important in hydrogen fuel cell?
In addition to the cost of purchase, operating costs also play an important role in the cost-effectiveness and acceptance of a propulsion technology. In hydrogen fuel cell cars, these costs are not least dependent on the price of the fuel.
Why are hydrogen fuel cells so expensive?
In addition to small volumes, which means that production is still to be industrialized, there’s also the question of the need for the precious metal, platinum , which acts as a catalyst during power generation. The amount of platinum needed for vehicle fuel cells has already been greatly reduced. “The general goal is to bring down the price of hydrogen-powered cars to a similar level to that of other electric cars,” explains Rücker.
How long does it take for a hydrogen tank to charge?
Depending on the charging station and battery capacity, fully electric vehicles currently require between 30 minutes and several hours for a full charge. The hydrogen tanks of fuel cell cars, on the other hand, are full and ready to go again in less than five minutes. For users, this brings vehicle availability and flexibility into line with those of a conventional car.
