The objective of the program is to clarify the molecular basis of electrocatalysis and thereby to provide the necessary scientific framework for the optimization of fuel cell electrodes. Hydrogen oxidation and reduction, the reduction of oxygen, and the oxidation of formic acid, a soluble organic substance, were selected for these studiees because of their relevance to fuel cell systems and because of their relative simplicity. The electrodes used range from amalgams to III-V semiconducting compounds. The approach is to resolve the overall reaction on any given electrode into the elementary steps of adsorption, electron transfer, chemical combination of free radicals, etc., and to determine how the parameters governing the rates of these various steps are related to the electrode composition and structure.
