摘要
本文提出制备磷酸燃料电池的电催化剂和气体扩散电极的新方法。用该方法制备的气体扩散电极在１００％磷酸电解质和１５０℃条件下，其氧气还原的电化学性能与美国Ｇｉｎｅｒ公司出产的商品气体扩散电极相比较具有更高的电化学活性。实验结果表明用此方法制各的电催化剂和气体扩散电极不仅简化了制备程序，而且由于避免了添加一些有机物或表面活性剂，提高了其组成的纯度，改进了气体扩散电极的电化学性能，因而具有较高的实用价值。
The paper offered a new method of preparing the electrocatalyst and manufacturing the gasdiffusion electrodes for phosphoric acid fuel cells(PAFC).The electrochemical performances of resulting electrodes in concentrated phosphoric acid for oxygen reduction at 150℃ compared with the commercial electrodes (Giner Inc.U.S.A)are evaluated.The results show that the purity of the electrocatalyst is higher and it is unnecessary to add any organic materials or surfactant in the process of manufacturing the gas-diffusion electrodes.So the manufacturing method is simplified and the electrochemical performance is greatly improved.
