Development of a polymeric micro fuel cell containing laser-micromachined flow channels

This paper presents the development of a micro fuel cell (μFC) by polymeric micromachining technique. The membrane electrode assembly (MEA) is embedded in a gold-coated polymethyl methacrylate (PMMA) substrate, on which the gas flow channels are fabricated by laser micromachining. The special Gaussi...
