Abstract
Not Available Fuel cells offer the potential to dramatically reduce environmental pollution as well as our dependence on foreign oil. They are actively being developed as alternated energy sources for transportation, stationary and military applications. The degradation of oxygen electrode catalysts (e.g., Pt, Ag, and others) and corrosions of carbon substrate make commercialization of present fuel cells economically unattractive. In addition, the fuel (methanol, ethanol) crossover to cathodes causes severe thermal management and cell voltage drop due to oxidation of fuel at the platinized cathode. In order to eliminate/minimize these effects; alternate inexpensive and stable catalysts are needed. Initial work has shown that metal macrocyclic complexes are promising candidates for improved O2 reduction catalysts in fuel cells, relative to present platinum catalysts. In this proposed program, we will evaluate these complexes in PEM fuel cells. The chemical and electrochemical performance and stability in the fuel cell environment will be examined.
