摘要：Investigating highly effective electrocatalysts for high-temperature proton exchange membrane fuel cells(HT-PEMFC)requires the resistance to phosphate acid(PA)poisoning at cathodic oxygen reduction reaction(ORR).Recent advancements in catalysts have focused on alleviating phosphoric anion adsorption on Pt-based catalysts with modified electronic structure or catalytic interface and developing Fe-N-C based catalysts with immunity of PA ***-N-C-based catalysts have emerged as promising alternatives to Pt-based catalysts,offering significant potential to overcome the characteristic adsorption of phosphate anion on *** overview of these developments provides insights into catalytic mechanisms and facilitates the design of more efficient *** review begins with an exploration of basic poisoning principles,followed by a critical summary of characterization techniques employed to identified the underlying mechanism of poisoning *** is then directed to endeavors aimed at enhancing the HT-PEMFC performance by well-designed ***,the opportunities and challenges in developing the anti-PA poisoning strategy and practical HT-PEMFC is *** these discussions,a comprehensive understanding of PA-poisoning bottlenecks and inspire future research directions is aim to provided.
