More Progress for Automotive-Oriented Direct Ammonia Fuel Cells

Shimshon Gottesfeld’s paper The Direct Ammonia Fuel Cell and a Common Pattern of Electrocatalytic Processes leads with a big number: “A record power density of 450 mW/cm2 has been demonstrated for a direct ammonia fuel cell [DAFC] using an alkaline membrane electrolyte.”  We know it’s big because it’s 80% higher than the 250 mW/cm2 that Gottesfeld’s team had achieved in the fall of 2017 and that Gottesfeld, Adjunct Professor of Chemical Engineering at the University of Delaware, reported at the November 2017 NH3 Energy+ Topical Conference.


Direct Ammonia Fuel Cell Utilizing an OH- Ion Conducting Membrane Electrolyte

We describe the techno-economic background and the R&D work scheduled for the ARPA-E project “Direct Ammonia Fuel Cells (DAFCs) for Transportation Applications,” which is about to start under the REFUEL program. The project is led by Shimshon Gottesfeld & Yushan Yan, University of Delaware, Jia Wang & Radoslav Adzic, Brookhaven National Laboratory, Chulsung Bae, Rensselaer Polytechnic Institute, and Bamdad Bahar, Xergy Inc. The multidisciplinary R&D work scheduled will cover the fields of advanced membrane and electrocatalyst development, MEA development and fabrication, and stack engineering. The latter two activities will be supported by work at POCellTech, with Miles Page as lead.…
