摘要
由于铂基催化剂在氧气还原和氢气氧化反应中具有高活性,因此经常被用于质子交换膜燃料电池。然而,这些催化剂很容易被一氧化碳毒害,导致燃料电池性能显著下降。使用耐 CO 催化剂可以有效解决这一问题。本文简要讨论了 CO 中毒机理和抗中毒策略。主要从三个方面介绍了耐 CO 催化剂的研究进展:铂合金催化剂、金属氧化物复合催化剂和阻挡层覆盖催化剂。此外,还讨论了近年来各种催化剂的优势和局限性。在催化剂表面覆盖多孔封端层可以有效提高催化剂的 CO 耐受性,这可能是开发 CO 耐受性以外的抗中毒催化剂的一种有前途的方法。最后,介绍了耐一氧化碳燃料电池催化剂的未来发展前景。
Advances in CO-tolerant anode catalysts for proton exchange membrane fuel cells
Pt-based catalysts are often used in a proton exchange membrane fuel cell due to their high activities to oxygen reduction and hydrogen oxidation reaction. However, these catalysts are easily poisoned by CO, resulting in a significant reduction of fuel cell performance. The use of CO-tolerant catalysts can effectively solve this problem. The CO poisoning mechanism and anti-poisoning strategies were briefly discussed in this article. It mainly focused on the research progress on CO-tolerant catalysts in three aspects: Pt alloy catalysts, metal oxide composite catalysts, and blocking layer covered catalysts. The advantages and limitations of various catalysts in recent years were also discussed. Creating a porous blocking layer covered on the surface of the catalyst can effectively enhance the CO-tolerance of the catalysts which could be a promising approach for developing anti-poison catalysts other than CO-tolerance. Finally, the prospects for future development of CO-tolerant fuel cell catalysts were described.
