Cyclic voltammetry ( cv ) in sulphuric acid solution and dimethyl ether solution is employed to characterize the catalytic activity of the electrocatalysts ; transmission electron microscopy ( tem ) and x - ray diffraction are employed to characterize the microstructure of the electrocatalysts ; the electrochemical characteristics of the direct dimethyl ether fuel cells ( ddfc ) made from the electrocatalysts are tested by arbin fuel cell test systems 在h2so4溶液中采用循环伏安对催化剂的电化学行为进行了评价;在饱和二甲醚溶液中采用循环伏安研究了pt / c催化剂对二甲醚氧化性能;通过透射电子显微镜( tem )和x射线衍射仪( xrd )分析了催化剂的表面物理特征;通过arbin燃料电池系统对催化剂制备二甲醚燃料电池进行评价。
