dc.description.abstract | MEMS fuel cell system was designed and fabricated for a portable power source in the present study. The system consists of a methanol-steam reformer, catalytic combustor, preferential oxidation (PROX) reactor, and polymer electrolyte membrane fuel cell (PEMFC). Methanol reformer is an essential part for hydrogen supply, in which a pre-heater, vaporizing/reforming channels and catalytic combustor were integrated. All components were fabricated using MEMS fabrication technologies combined with catalyst loading processes. Performance of the MEMS fuel cell system was measured with the optimal conditions of the reformer and PROX. Power density was 195 mW/cm(2) when the potential was 0.64V. The performance was low compared to the result for pure hydrogen because the feed at the fuel cell included undesired CO, CO(2), and N(2). MEMS fuel cell system with a weight specific energy density of 225 W h/kg was accomplished as an alternative micro power source. (C) 2008 Elsevier B.V. All rights reserved. | - |
