In the past few years of intensive research on Anion-Exchange Membrane (AEM) Fuel Cells (AEMFCs), amazing progress has been reported. Novel highly stable functional groups for AEMs1-4 and PGM-free catalysts5-7 were developed, new AEMFCs based on CRM-free catalysts were successfully demonstrated8, AEMFC lifetime of 5,000-15,000 hours was theoretically demonstrated for the first time9-10, and cell lifetime of 2,000 hours was experimentally proven11. Altogether, the research community has made very impressive progress in such a short time. However, due to the degradation of AEMs, the operation of AEMFCs has been limited only to low temperatures, mainly below 80 ℃. We have recently presented the first results of AEMFCs successfully operated at cell temperatures above 100 ℃12-16. At these high temperatures, we could achieve hydroxide conductivities close to 300 mS/cm17. The first results are very encouraging and represent a significant landmark for the technology, opening a wide door for a new field of study we call the High-Temperature AEMFCs (“HT-AEMFCs”). In this talk, I will present the latest achievements in the HT-AEMFCs.
