Full Answer
How does the Faraday constant relate to the number of electrons?
This relation holds because the amount of charge of a mole of electrons is equal to the amount of charge in one electron multiplied by the number of electrons in a mole. One common use of the Faraday constant is electrolysis.
What does the Faraday constant 96 485 C mean?
The known Faraday constant 96,485 C/mol denoted by the symbol F, or also called 1 F, corresponds to the amount of electricity that is carried by 1 mol of electrons. The number comes from the charge of a single electron 1.6023 × 10 −19 C times the number of electrons in 1 mol, given by the Avogadro number 6.02 × 10 23 electrons.

Contrary to the beliefs of generations of chemistry students, Avogadro’s number—the number of particles in a unit known as a mole—was not discovered by Amadeo Avogadro (1776-1856). Avogadro was a lawyer who became interested in mathematics and physics, and in 1820 he became the first professor of physics in Italy.

What is SOFC in electrochemistry?
A solid oxide fuel cell (SOFC) is an electrochemical device that converts chemical energy of a fuel and an oxidant gas (air) directly into electricity without irreversible oxidation. It can be treated thermodynamically in terms of the free enthalpy of the reaction of the fuel with oxidant. Hydrogen and oxygen are used to illustrate the simplest case in the early part (Section 3.2) of this chapter. This treatment allows the calculation of the reversible work at equilibrium for the reversible reaction. Heat must also be transferred reversibly to the surrounding environment in this instance.
