Ammonia is one of the most important and widely produced chemicals worldwide, and a primary ingredient for fertilizer and hydrogen carrier for energy supplying. Currently, owing to the kinetic and thermodynamic restrictions of ammonia synthesis reaction, most of ammonia is produced under conditions of temperature up to 400-500 oC and pressure up to 100-200 bar (Haber-Bosch process), resulting to intensive energy input and accounting for 3% of global energy consumption annually. Although numerous NH3 synthesis catalysts with high activity has been developed recently, but the yield of NH3 is still low. Membrane reactor which can timely and exclusively remove trace…

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.

Progress for Low-Temperature Direct Ammonia Fuel Cells
Speaking at the NH3 Energy+ Topical Conference last month, University of Delaware Adjunct Professor Shimshon Gottesfeld reported on progress made by the university’s direct ammonia fuel cell (DAFC) project. Evidently, the UDel team is now a big step closer to its goal of establishing the DAFC as a viable automotive power plant.
