Research Progress and Improvement Strategies of Phosphoric Acid-doped High-temperature Proton Exchange Membranes
质子交换膜燃料电池(PEMFC)具有能量转化效率高、启动速度快及操作维护方便等突出优势.在120～250℃范围内运行的高温质子交换膜燃料电池(HT-PEMFC)无需依靠水进行质子传导,可以有效简化水管理系统,同时提升电极反应动力学并强化铂基电催化剂的抗中毒能力.目前,磷酸(PA)掺杂的聚苯并咪唑(PBI)膜是HT-PEMFC的首选隔膜材料,但其面临着抗氧化稳定性不佳以及PA流失等关键挑战.本文首先阐明了PA掺杂型高温质子交换膜(HT-PEM)的传输机制,并基于近十年的研究进展对此类材料进行了系统分类;然后,重点剖析了HT-PEM面临的关键技术挑战及其应对策略,并展望了未来的发展趋势.
Proton exchange membrane fuel cell(PEMFC)has outstanding advantages such as high energy conversion efficiency,fast start-up speed,easy operation and maintenance.In the temperature range of 120 to 250℃,the operation of high-temperature proton exchange membrane fuel cells(HT-PEMFC)does not rely on the presence of water for proton conduction.This can effectively simplify the water management system,enhance the kinetics of electrode reactions,and strengthen the anti-poisoning ability of platinum-based electrocatalysts.At present,phosphoric acid(PA)-doped polybenzimidazole(PBI)membrane is the preferred membrane material in HT-PEMFC,but it faces key challenges,such as poor antioxidant stability and PA loss.In this review,the transport mechanism of PA-doped high-temperature proton exchange membranes(HT-PEM)is first clarified,and such materials are systematically classified based on the research progress in the past 10 years.Finally,the key technical challenges and coping strategies of HT-PEM are analyzed,and the future development trend is prospected.
