Fuel cells are an attractive alternative to batteries for portable electronic devices. Micro-fuel cells produced using micro- or nanofabrication methods hold promise for being highly efficient and low cost. Most micro-fuel cells include micromachined fuel cell components combined with conventional macro membrane electrode assemblies. To improve the performance of the electrode thin films, the use of nanoimprint technologies was described to fabricate electrodes with increased active surface areas. This is an abstract of a paper presented at the AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
