A high-temperature anion-exchange membrane fuel cell

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.
