| 摘 要： | 1 INTRODUCTIONIn recent years, the application of the roomtemperature type ( < 100 ℃) polymer electrolytemembrane fuel cells(PEMFCs) as a primary powersource in electric vehicles and portable equipmentsetc has received increasing attention[1 4]. Usuallyin a PEMFC system, platinum is chosen as the e lectrode electrocatalyst, however, it results in ahigh cost PEMFC system for commercialization be cause Pt is a high cost, source limit metal. So,looking fo…

| Abstract: | The electrocatalytic properties of hydrogen storage alloy(HSA) MlNi3.65 Co0.85 Al0.3 Mn0.3 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/cm2 at 0.5 V and 232.4 mA/cm2 at 0.2 V, and its power density reaches the maximum value of 84 mW/cm2. The influence of operating temperature and hydrogen pressure on the electrocatalytic behavior of HSA anode MEA is also discussed. At 60 ℃ under 2.02× 105 Pa H2, the HSA anode shows the best electrochemical properties. |
