| Abstract: | A novel design and microfabrication were developed for a micro Proton Exchange Membrane (PEM) fuel cell with a cross section of 5 cm2 and thickness (for a single cell) of about 800  m. A new design and fabrication processes were developed for both flow field plate and MEA parts. Air flows were completed in hydrogen fuel cells with low input pressure and low velocity. Performance tests of polarization curves and power density distribution were conducted and discussed.Part of this work was presented at the first ASME Conference on Fuel Cell Science, Engineering and Technology, April 21–23, 2003, Rochester, New York, USAThis work was performed in University Microsystem Laboratory, Center for Nanoscience and Technology, National Sun Yat-Sen University. The effort is sponsored by the National Science Council (NSC), Taiwan, ROC, Grant numbers NSC 91-2218-E-110-009 and 91-2218-E-110-010. |
