【Abstract】 The porous carbon plate was made by using carbon fiber,refined cotton and phenol resin as raw materials. The raw materials was mixed by screening method,then pressed into shape at 170?℃,and finally sintered in inert atmosphere at high temperature to make the plate. The effects of composition and pressing pressure on the gas permeability and electric resistivity of the plate were examined. Good performance of the plate was observed in phosphoric acid fuel cell (PAFC).更多还原
