摘要
阐述了近些年来在提高质子交换膜燃料电池催化剂寿命方面的研究进展。提高催化剂寿命,关键在于提高催化剂金属的电化学氧化还原电位,以及提高催化剂载体的化学和电化学稳定性。同时,研究表明,提高金属催化剂颗粒与载体间的作用力和优化燃料电池运行过程中的操作也是提高催化剂寿命的比较有前景研究方向之一。
Improving the durability is one of the key factors that impede the commercialization of proton exchange membrane fuel cells（PEMFC）.In this paper,some methods toward improving the catalyst durability were discussed.The durability of catalysts was inherently determined by the electrochemical life of metallic catalyst,the chemical and electrochemical stability of metallic catalyst and its support.On the other hand,enhancement of the interaction between metallic catalyst and the support and optimization of the operation process of fuel cells were also promising research directions.
