A proton-conducting anode Ni/GDC-BCY was proposed for a high power density Solid-Oxide-Fuel-Cell. The electric characteristics were investigated through alternative current impedance measurement. The most striking feature is that, using the anode Ni/GDC-BCY(90%:10%), the polarized resistance which indicates an overpotential in anode is reduced to the half of that of the conventional anode Ni/GDC. It is clarified that since much amount of hydrogen might be adsorbed on the surface of each BCY particulate distributed in the anode, adsorbed oxygen which is transferred as oxide ions through GDC particulates has large chance to react with the adsorbed hydrogen.
