A novel design and microfabrication were developed for a micro PEM (Proton Exchange Membrane) fuel cell with a cross section of 5cm2 and thickness (for a single cell) of about 800 μm. 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.
