Researchers at the Technion – Israel Institute of Technology and Tianjin University in China say they have developed a new approach that could make hydrogen fuel cells more affordable, durable and efficient while allowing them to operate with ambient air.
Their findings, published in Nature Energy, focus on anion-exchange membrane fuel cells, or AEMFCs, which generate electricity through a reaction between hydrogen and oxygen. Unlike some conventional fuel cell technologies, AEMFCs can use cheaper and more abundant materials, potentially reducing system costs.
The technology is being studied for use in transportation, aviation, aerospace, drones, distributed energy systems, backup power and electricity generation in remote areas.
The study was led by Prof. Dario Dekel of the Technion’s Wolfson Faculty of Chemical Engineering and the Nancy and Stephen Grand Technion Energy Program; Prof. Michael Guiver, a polymer membrane expert at Tianjin University; Dr. Karam Yassin, manager of the Technion’s Central Hydrogen Technologies Laboratory; and Dr. Sapir Willdorf-Cohen, a researcher in Dekel’s group.
