Abstract

The main challenge preventing the broad commercial use of polymer electrolyte membrane fuel cells (PEMFCs) is the dependence on noble metals, specifically electrocatalyst (EC) based on platinum (Pt) at the cathode, which is indispensable for assisting the oxygen reduction reaction (ORR) in fuel cells (FCs). Research on EC-containing non-noble metal (NNM) has been considerable over the past few decades to minimize costs and reduce the excessive loading of EC based on Pt. This review is aimed at improving the reliability and stability of non-precious metal EC. To achieve a feasible ORR, Pt-based EC is crucial for the widespread commercial applications of PEMFCs. The review emphasizes improving ORR performance, stability, and cost-effectiveness in catalysts that are not precious metals. The article examines the advancements in non-precious nanomaterial-based EC, highlighting different types that have improved ORR efficiency. The review suggests future possibilities and directions for further improvement in designing and constructing EC with high efficiency and low costs for PEMFCs.

非贵重氧还原反应电催化剂的类型、性能及应用综述

阻碍聚合物电解质膜燃料电池（pemfc）广泛商业应用的主要挑战是对贵金属的依赖，特别是阴极上基于铂（Pt）的电催化剂（EC），这对于燃料电池（fc）中的氧还原反应（ORR）是必不可少的。在过去的几十年里，为了最大限度地降低成本和减少铂基电催化材料的过载，对含非贵金属电催化材料（NNM）进行了大量的研究。本文旨在提高非贵金属电催化材料的可靠性和稳定性。为了实现可行的ORR，基于pet的EC对于pemfc的广泛商业应用至关重要。该综述强调在非贵金属催化剂中提高ORR的性能、稳定性和成本效益。本文考察了非贵重纳米材料基EC的进展，重点介绍了提高ORR效率的不同类型。本文综述了高效、低成本设计和构建pemfc的可能性和进一步改进的方向。
