The flow channels on the bipolar plates are 2 mm high and 2mm wide. The metal bipolar plates are plated with corrosion-resistant metal, within 10μm, by electroless plating. In addition to the metal bipolar plates, low thermal conductivity of bakelite as side boards, allowing the air in and out, and MEA whose response area is 5×5cm2 are used to assemble a PEMFC (Proton Exchange Membrane Fuel Cell). This study successful assembled the metal bipolar plate fuel cell stack with a maximum power density of 4933.6mW/cm2 and a maximum current density of 620mA/cm2. The performance of the cell stack assembled in this study is stable and consistent, achieving the purpose of developing renewable energy which can be sustained forever.
