The cost of components must be reduced to make large scale production of microbial fuel cells economical. Using Pt on a carbon support is the most efficient catalyst for oxygen reduction. Because Pt is expensive, better information on how to optimize the catalyst characteristics for improved performance and lower costs is needed. The effects of Pt-loading, electrode structure and bio-film on cathode performance were studied. The Pt/C air cathode was prepared by pasting a mixture of Pt/C catalyst with Nafion™ or PTFE solution into a wetting-proofed carbon cloth. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
