摘要：
The electrocatalytic properties of hydrogen storage alloy(HSA) MlN(3.65)Co(0.85)Al(0.3)Mn(0.3) substituting Pt as anode electrocatalyst of PEMFC was investigated. It is found that, after being optimized, the electrocatalytic abilities of the HSA is reasonably good, the current density of the HSA anode membrane and electrode assembly (MEA) reaches 168 mA/cm(2) at 0.5 V and 232.4 mA/cm(2) at 0.2 V, and its power density reaches the maximum value of 84 mW/cm(2). The influence of operating temperature and hydrogen pressure on the electrocatalytic behavior of HSA anode MEA is also discussed. At 60 degrees C under 2.02 X 10(5) Pa H-2, the HSA anode shows the best electrochemical properties.
