Guest Lecture Dario Dekel - "Review of the Performance of Anion Exchange Membrane Fuel Cells"
Please join the Department of Materials Science in welcoming guest speaker Professor Dario R. Dekel, Chemical Engineering Associate Professor and Director of the TEEM lab (Technion Electrochemical Energy based on Membranes). Professor Dekel is visiting from the Grand Technion Energy Program (GTEP) at the Technion – Israel Institute of Technology located in Haifa, ISRAEL.
The Alkaline Anion Exchange Membrane Fuel Cells (AEM-FCs) have recently received increasing attention since in principle, they allow for the use of non-precious metal catalysts, which dramatically reduces the cost per kW of power. Until recently the main barrier in the development of AEM-FCs was the availability of highly conductive AEMs. Latest improvements done in this front are impressive, and some of the new developed AEMs already reached anion conductivities close to those of Nafion for acidic PEM-FCs. In the past four years an increasing number of research studies has been published showing cell performance results from AEM-FC tests.First results are very promising. However, in spite of the advances in AEM development, performance of AEM-FCs is still not maximized. In addition, due to the lack of suitable electrocatalysts for the hydrogen oxidation reaction (HOR), most of the AEM-FC tests found in the literature are still based on Pt as anode electrocatalyst. In this talk a review of the performance results published in the AEMFC field will be presented. Technion research focus on polymers and electrocatalysts for AEM-FC (as well as for AEM-Redox Flow Batteries) will be also discussed.
