Time-Dependent ("Mechanical"), Nonbiological Catalysis. 3. A Readily Prepared, Convergent, Oxygen-Reduction Electrocatalyst
The development of oxygen reduction catalysts for application in H2/O2 fuel cells has attracted considerable recent interest . This interest can be attributed to a growing recognition that such cells offer a potential alternative, nonpolluting power source, especially in transportation applications, where their high-power densities allow them to compete with the internal combustion engine. H2/O2 fuel cells are currently used in buses and various other public transportation vehicles in several cities around the world . Efforts are being made to extend their utility to automobiles. Finding efficient and, more importantly, economical dioxygen reduction catalysts is a significant part of this effort. Much work has focused on the development of new, inexpensive, non-noble metal electrocatalysts.
