The concentration of such species, hence, the pH of the electrolyte, affect the cell potential. Again such a dependence can be calculated using the Nernst equation. As an example, let us consider the partial oxidation of ethanol in alkaline environments, a reaction exploited for energy production by Direct Ethanol Fuel Cells (DEFC). CH3 CH2 OH þ O2 þ OHÀ ! CH3 COOÀ þ 2H2 O ð2:9Þ The reaction Eq. 9) occurs in alkaline environments and the OH- species is a reactant. In a first approximation, we can substitute the activity with the concentration, furthermore considering that four electrons are exchanged in Eq.

The cell potential may hence be considered as the contribution of the sum of a potential contribution coming from the half cell anode (Eq. 2) and the half cell cathode reactions (Eq. 3), respectively. As in physical systems only potential differences matter, there is no chance to define an absolute potential scale for half reactions. Nevertheless for practical purposes the problem can be solved tabulating all half cell potentials with respect to the same standard electrode providing a practical working framework.
