To lower platinum loading in electrodes for polymer electrolyte membrane fuel cell,a new thin electrode fabrication technique(TEFT) was developed in this work.A series of low Pt loading electrodes with smooth and uniformed surface were fabricated by the TEFT.As a result,the maximum power density of the cell with platinum loading of 1 mg/cm 2 and Nafion 117 membrane as electrolyte was up to 0.3 W.cm -2 .Moreover,the effects of PTFE and Nafion content in cathodes on the performance of PEMFC with low Pt loading electrodes(1 mg Pt/cm 2)were examined systematically.
