X-ray Diffraction(XRD) indicated the powders doped 10%Y were single perovskite phase. The powders doped 15%Y and 10%Sm didn`t have Y2O3 and Sm2O3 respectively. It was concluded that solid sulubility limit of Y is above 0.15 and that of Sm is above 0.10 in BaCeO3. By laser light scattering paticle size analysis indicated that average particle size of powders changed larger and particles that particle size is about 5μm accounted for the most quantitatively after calcination. TG-DSC analysis displayed the sintering temperature of proton conductors was about 1360℃. SEM showed these proton conductors were composed of two particles whose size ranged from 1μm to 10μm. The Dehydrogenation result indicated deydrogenation current getted higher when the temperature of Al melt,water vapor pressure and external voltage getted higher independently. By CaZr0.9In0.1O3-α hydrogen sensor the hydrogen activity was 0.0536 and 0.0445 mlH2/100gAl when the temperature of Al melt was 780℃, PH2O was apart 4122.8Pa and 4366.0Pa.
