Development of a Direct Ammonia Fueled Hydrogen Membrane Fuel Cell

Hydrogen membrane fuel cells, HMFC, were fabricated by RF sputtering deposition of BaCe 0.8 Y 0.2 O 3- d thin films on Pd solid anode. The HMFC can give OCF of 1.1 V and peak power density of 300 mW cm -2 at 600°C with H 2 fuels. On the other hand, the direct NH 3 fuel HMFC reveals OCV of 0.95 V and peak power density of 80 mW cm -2 at 600°C. The impedance spectroscopy reveals that anodic polarization is a main contribution to the loss in HMFC.
