| 摘 要： | 总结了质子交换膜燃料电池(PEMFC)用Pt/C催化剂在长时间运行过程中性能衰减的主要原因及近年来提高Pt催化剂稳定性的方法.性能衰减的主要原因有:Pt在碳载体上的迁移、团聚;Pt纳米粒子的溶解再沉积;Pt中毒及碳载体的腐蚀.选用更稳定的载体和Pt合金化是提高稳定性研究的重点,通过对Pt进行封装也可提高Pt/C催化剂的稳定性.

| Abstract: | The main reasons of performance degradation of Pt/C catalysts for proton exchange membrane fuel cell(PEMFC)in long term working and the method to improve the stability of Pt catalyst were summarized.The main reasons of performance degradation including the shift and agglomeration of Pt on the carbon support,the dissolution and redeposition of Pt nano-particles,the poisoning of Pt and carbon support corrosion.The choosing of more stable support and alloying of Pt were the research emphasis of stability impro... |
