This talk will begin with a brief introduction into the various types of fuel cells and the problems that confront attempts to commercialize them. One of the biggest hurdles preventing their implementation for a wide variety of applications is the fact that only H₂ could be used as the fuel in many types. Since the vast majority of H₂ is generated by reforming hydrocarbons, it would be much simpler and more efficient if one could operate fuel cells on existing hydrocarbon fuels without reforming. For SOFC with conventional, Ni-based anodes, the primary limitation for direct oxidation of hydrocarbons in an SOFC is the propensity of Ni to catalyze carbon formation. To avoid this, work at Penn has focused on replacing Ni with other catalytic and electronically conductive materials. In this presentation, I will describe recent results from our laboratories on the synthesis and characterization of these novel anodes. Possibilities for commercialization will be discussed.
