Reversible electromotive force and electrochemical reaction rate of fuel cells

(1) The reversible electromotive force of the battery. The heat-electric energy conversion relationship followed by the fuel cell is ΔG=-nFEr     (1-1) When the activities of the substances participating in the reaction are all equal to 1, rewrite as ΔGΘ=-nFErΘ     (1-2) In the formula: Er is the reversible electromotive force (or reversible potential) of the battery reaction; ΔG […]
