In this study, we used low-cost, lightweight aluminum alloy bipolar plate on proton exchange membrane fuel cell(PEMFC) stack. Aluminum alloy has good heat Thermal conductivity and mechanical strength. But, aluminum alloy surface oxides lead to poor conductivity, high contact resistance. So we using Au-coated on aluminum alloy bipolar plate surface. Assembled into a single cell and 4-cells stack to measure performance. At H2/Air stoichimotry 1.2/4.0 and humidification temperature of 60 ℃ for best performance by single cell 61.6W and stack maximum power 286W. The dynamic load test had a good response. Finally, the metal bipolar plate to set a long-term test to ensure the stability of the single cell output is no recession.
