WebGibbs free energy (G) is a measure of the maximum available work that can be derived from any system under ... A substantially larger fraction could be extracted by a fuel cell. … WebAnd this voltage is the Standard Cell Potential. So E naught of the cell is equal to positive 1.10 volts. And the Standard Cell Potential depends on the potentials for the two half reactions that make up the cell. So if we know the potentials for the half reactions that make up the cell, we can calculate the standard potential of any galvanic cell.
