在过去的几年里，阴离子交换膜(AEMS)的发展导致了氢氧化物电导率的显著增加，最终导致了阴离子交换膜燃料电池(AEMFC)在低工作温度(通常在40-80℃)下性能的显著改善。除了这些显著的成就，文献中没有任何关于在100℃以上工作的AEMFC的工作，尽管各种模型一致认为在更高的电池温度下工作可能会带来许多显著的优势。在这项工作中，我们介绍了第一个在110℃测试的高温AEMFC(HT-AEMFC)。HT-AEMFC具有高性能，在0.8V时测得的峰值功率密度为2.1 W cm(-2)，电流密度高达574 mA cm(-2)。这项初步工作代表着燃料电池技术研究和开发的一个重要里程碑，为我们以下称为HT-AEMFC的新研究领域打开了一扇大门。
In the past few years, developments in anion exchange membranes (AEMs) have led to a significant increase in hydroxide conductivities, ultimately yielding striking improvements in the performance of anion exchange membrane fuel cells (AEMFCs) at low operating temperatures, usually at 40-80 degrees C. Aside from these remarkable achievements, the literature is void of any work on AEMFCs operated at temperatures above 100 degrees C, despite the consensus from various models remarking that working at higher cell temperatures may lead to many significant advantages. In this work, we present the first high-temperature AEMFC (HT-AEMFC) tested at 110 degrees C. The HT-AEMFC exhibits high performance, with a peak power density of 2.1 W cm(-2) and a current density of as high as 574 mA cm(-2) measured at 0.8 V. This initial work represents a significant landmark for the research and development of the fuel cell technology, opening a wide door for a new field of research we call hereafter, HT-AEMFCs.
