Abstract

Proton exchange membrane fuel cells (PEMFCs) are considered to be a clean energy technology to replace conventional internal combustion engines in automobiles. PEMFCs undergo a complex degradation involving multiple dimensions, materials, and factors. This review focuses on the decay of key materials of PEMFCs after durability tests longer than 2000 hours, providing an in-depth look at degradation behaviors at the material and component levels. The H2-crossover current, ohmic resistance, kinetics current and the limiting current were thus identified as core primary factors from the perspective of performance and stability. Besides, the critical aging factors of key components were defined as where significant numerical changes occur during the aging process, causing any one or more of the four core primary factors to change by more than 10% in physical or chemical parameters.

关于 PEM 燃料电池关键部件耐久性的综述
质子交换膜燃料电池(PEMFCs)被认为是一种清洁能源技术,可取代传统的汽车内燃机。PEMFC 的降解过程非常复杂,涉及多个层面、材料和因素。本综述重点关注 PEMFC 关键材料在超过 2000 小时的耐久性测试后的衰减情况,深入探讨材料和组件层面的降解行为。因此,从性能和稳定性的角度来看,H2-交叉电流、欧姆电阻、动力学电流和极限电流被确定为核心的主要因素。此外,关键元件的临界老化因素被定义为在老化过程中发生重大数值变化,导致四个核心主要因素中的任何一个或多个物理或化学参数变化超过 10%。
