摘要
To meet challenges associated with climate changes due to the continuous increase in global energy demand, implementation of hydrogen and fuel cell technologies, especially the polymer electrolyte membrane type, are recognized as potential solutions. The high temperature polymer electrolyte membrane fuel cell based on acid doped polybenzimidazoles has attracted enormous R&D attention due to the simplified construction and operation of the power system. In order to improve the reliability and lifetime of the technology, studies on material degradation and mitigation are essential. The present work is a comprehensive review of the current knowledge on degradation mechanisms of the fuel cell components including the acid loss, polymer oxidation and catalyst instability due to the metal dissolution and carbon support corrosion. The durability results are updated according to the categories of steady state and dynamic operations. Durability protocols, diagnostic techniques and mitigation strategies are also discussed.
