摘要：

近年来，聚合物电解质膜燃料电池和电解器的高温运行已经有了大量研究工作，并取得了很大的进展。在本演讲中，首先介绍了重要的研究工作和最近的进展。公认的关键问题包括铂基催化剂、酸的保留和长期耐久性。在温和的温度范围内，在连续操作下观察到优异的聚合物耐久性。随着负载或热循环，尤其是在开路电压作用下，由于酸的损耗和催化剂的降解增加，耐久性问题更为关键。进一步地概述了今后的工作方向。

ABSTRACT：

High temperature operation of polymer electrolyte membrane fuel cells and electrolysers has in last years motivated extensive research activities with great progress. In this talk, significant efforts and recent progress are first presented. The recognized critical issues include platinum based catalysts, acid retention and long term durability. Excellent polymer durability was observed under continuous operation in the mild temperature range. With load or thermal cycling, the durability issues are more critical due to the increased acid loss and catalyst degradation particularly under open circuit voltage operation. Further efforts are outlined to the future work.
