A constant increase in global emission standard is causing fuel cell (FC) technology to gain importance. Over the last two decades, a great deal of research has been focused on developing more active catalysts to boost the performance of high-temperature polymer electrolyte membrane fuel cells (HT-PEMFC), as well as their durability. Due to material degradation at high-temperature conditions, catalyst design becomes challenging. Two main approaches are suggested: (i) alloying platinum (Pt) with low-cost transition metals to reduce Pt usage, and (ii) developing novel catalyst support that anchor metal particles more efficiently while inhibiting corrosion phenomena. In this comprehensive review, the most recent platinum group metal (PGM) and platinum group metal free (PGM-free) catalyst development is detailed, as well as the development of alternative carbon (C) supports for HT-PEMFCs.
全球排放标准的不断提高使得燃料电池（FC）技术变得愈发重要。在过去二十年中，大量研究聚焦于开发更具活性的催化剂，以提升高温聚合物电解质膜燃料电池（HT-PEMFC）的性能及其耐久性。由于高温条件下材料会发生降解，催化剂设计颇具挑战性。为此提出了两种主要方法：（i）将铂（Pt）与低成本过渡金属合金化以减少Pt的用量，以及（ii）开发新型催化剂载体，更有效地锚定金属颗粒同时抑制腐蚀现象。在这篇综述中，详细介绍了最新的铂族金属（PGM）和无铂族金属（PGM-free）催化剂的发展情况，以及HT-PEMFC替代碳（C）载体的发展情况。
