Ammonia fuel cell using doped barium cerate proton conducting solid electrolytes

A comparative test using BCGP electrolyte showed that the doubly doped barium cerate electrolyte performed better than BCG electrolyte. Overall fuel cell performance characteristics were enhanced by approximately 40% under either hydrogen or ammonia fuels using BCGP electrolyte. At 700 °C using direct ammonia feed, power density reached 35 mW cm−2 at a current density of approximately 75 mA cm−2. Minimal loss of performance was noted over approximately 100 h on-stream in alternating hydrogen/ammonia fuels.
