Ever increasing energy demands and environmental concerns necessitate development of technologies which are clean, efficient and environmentally friendly such as hydrogen based proton exchange membrane (PEM) fuel cells. One of the technological challenges identified here is the slow kinetics of the oxygen reduction reaction (ORR) at the cathode. Platinum based catalysts currently used to catalyze ORR suffer from their high costs, limited availability and susceptibility to presence of poisons in the fuel. Our research effort has focused on development of alternative electrocatalyst materials for PEM fuel cells.
