摘要
在燃料电池膜反应器中 ,以盐酸水溶液为电解质研究了氧在多孔石墨阴极上的还原动力学。结果表明 ,影响还原反应速率的主要因素为氧气分压。根据实验结果 ,估算了反应级数 ,并初步分析了反应机理。
Kinetics of cathode reduction reaction of oxygen to hydrogen proxide was studied in a fuel cell reactor, while HCl aqueous solution was used as electrolyte, and graphite was used as catalyst. Results indicated that main factor for the reaction, which affected the reduction rate of oxygen on the cathode, was the partial pressure of oxygen, pH has little effect on the reduction rate. The rate-determine step for the reduction of oxygen was O 2+e -→O - 2
