阴离子交换膜燃料电池（AEMFC）是质子交换膜燃料电池（PEMFC）的重要替代品。然而，AEMFC涉及阳极上的缓慢氢氧化反应（HOR）。通过控制钌纳米颗粒的尺寸、使钌与铱合金化以及对金属纳米颗粒进行表面改性来开发提高HOR的催化剂，从而通过优化催化剂表面的氢结合能和双官能度来增强催化活性。本文综述了AEMFC阳极催化剂的研究进展。
Anion exchange membrane fuel cells (AEMFCs) are important alternatives to proton exchange membrane fuel cells (PEMFCs). However, AEMFCs involve slow hydrogen oxidation reaction (HOR) on the anode. Catalysts to improve the HOR were developed by control of ruthenium nanoparticle size, alloying ruthenium with iridium, and surface modification of metal nanoparticles, resulting in enhanced catalytic activity by optimizing hydrogen binding energy and bifunctionality of the catalyst surface. Here, the recent development of anode catalysts for AEMFCs is reviewed.
