The key materials of proton exchange membrane fuel cell, including electrocatalyst, electrode, proton exchange membrane (PEM) and bipolar plates are introduced. The basic fundamental and the stateofart of the key materials at home and abroad are described. The preparation methodes to electrocatalysts, such as colloid method, direct reduction method and ion exchange method, are also reviewed. Moreover, the characteristics of various electrode preparation methods are introduced. The new electrode design and promising manufacturing ways are indicated and the disadvantages of the present PEM are presented. The results of PEM degradation mechanism is given. The studies of Nafion/PTFE membrane, blending membrane and PBI membrane are reviewed. The development trends of the membrane in the medium and long terms are previewed. As for the bipolar plate material, the molding bipolar plates, swelling graphite bipolar plate and metallic bipolar plate are compared.
