Abstract

Combinatorial chemistry provides a means of rapidly screening electrocatalysts for use in fuel cells and related applications. The screening methods that have so far been applied to electrocatalyst arrays include indirect fluorescent detection, steady-state voltammetry, chronoamperometry, and scanning electrochemical microscopy. Several different types of anode and cathode electrocatalysts for polymer electrolyte membrane fuel cells have been studied by these techniques. Heuristic models based on mechanistic and spectroscopic studies of fuel cell catalysis are useful in guiding these searches for new catalyst compositions, and detailed studies of the catalysts already discovered can help to refine or augment these models. One of the outstanding challenges remaining in this area is to find ways to match more closely the synthesis/screening conditions of array catalysts with those of bulk catalysts used in real fuel cells.
