5. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell
Abstract : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). READ MORE
