磷酸掺杂型高温质子交换膜的研究进展与改进策略
Research Progress and Improvement Strategies of Phosphoric Acid-doped High-temperature Proton Exchange Membranes
摘要
Abstract
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.关键词
