Abstract :
Presented is a H2/air self-breathing miniature proton exchange membrane fuel cell (μPEMFC) stack. MEMS fabrication technology is used to complete both the single fuel cell and the stack of six cells electrically connected in series. The single-sided self-breathing μPEMFC stack with planar-layout configuration is realized for convenience of portable applications. In addition, the μPEMFC stack meets the requirement of miniaturized low cost mass fabrication. The characterization results show specific power as high as 0.21W/cm3, with which the MEMS μPEMFC stack is promising to be applied as a new generation of miniaturized hydrogen power source.
