PEMFC阳极抗CO性能研究进展

Research progress on anode CO-tolerance of PEMFC

利用碳氢化合物尤其是天然气重整制氢为PEMFC提供阳极反应气的一个突出问题是重整气中的微量CO对PEMFC阳极催化剂的毒化问题。通过简介CO的毒化机理,综述了目前广泛研究的各类抗CO毒化方法的研究进展,其中抗CO电催化剂仍是最具发展前景的方法。

The major problem of the reformate gas from hydrocarbons especially natural gas for PEMFC use is the anode CO-poisoning.In this paper,by introducing the CO-poisoning mechanism,the main methods for improving the CO-tolerant performance of PEMFC was reviewed,and the CO-tolerance electrocatalyst was still the most promising way.
