A high performance direct ammonia fuel cell using a mixed ionic and electronic conducting anode

A high performance direct ammonia fuel cell incorporating a doubly doped barium cerate electrolyte and a novel cermet anode consisting of europium doped barium cerate, a mixed ionic and electronic solid electrolyte, and Ni was studied. The catalytic activity of the cermet anodes was superior to that of Pt catalysts. The I–V and power density data suggest that the direct ammonia fuel cell could be operated at temperatures as low as 450 °C. The fuel cell was operated with ammonia as fuel in excess of 500 h without significant deterioration in performance.
