Catalyst Development for High Temperature Polymer Electrolyte Membrane Fuel Cell (HT-PEMFC) Applications.

A constant increase in global emission standards 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 supports that anchor metal particles more efficiently while inhibiting corrosion phenomena. In this comprehensive review, we detail the most recent Platinum Group Metal (PGM) and Platinum Group Metal Free (PGM-free) catalyst development, as well as the development of alternative carbon (C) supports for HT-PEMFCs.
