Abstract : The objective of this project was to develop new chemistry that could be applied to an efficient fuel cell operating directly on organic fuels under ambient or near-ambient conditions. The report summarizes scientific accomplishments, including the discoveries that (a) soluble metal complexes offer potential advantages over traditional metal surfaces for hydrocarbon oxidation, although simultaneously optimizing the rate and potential for such oxidations (as is needed for fuel cell application) is a significant challenge that has not yet been solved; (b) direct four-electron reduction of O2 has been achieved by a catalyst capable of multiple electron transfer; and (c) a new liquid feed fuel cell that operates directly on organic fuels such as methanol, and that includes a superacidic surfactant as an important component, has achieved levels of performance that significantly improve on previous work. Also included are bibliographic information for approximately 60 publications, presentations and patents resulting from work under this grant. jg p.1
