Ｐｔ／Ｃ气体扩散电极制备方法的探索马永林（青海教育学院，青海，西宁８１０００８）以Ｐｔ／Ｃ为电催化剂的气体扩散电极的制备方法是直接影响该电极电化学性能的重要因素。一般的制备方法是基于将Ｐｔ／Ｃ电催化剂和聚四氟乙烯以及某些有机物或表面活性剂的糊状物涂布...The various methods of manufacturing gas-diffusion electrodes are reviewed and a new method of preparing the Pt/C electrocatalyst and the gas-diffusion electrodes is explored in this paper. The electrochemical performance of resulting electrodes in concentrated phosphoric acid for oxygen reduction at 150℃ are compared with the commercial electrode which purched from Giner Inc. (U. S. A). The results show that the performance of the Pt/C electrodes which manufactured by the method in this paper has been greatly improved. Therefor, a fuel cell using such electrodes has high industrial value.
