Specimens of SrZr0.95Ga0.05O3-$delta$, SrZr0.95Y0.05O3-$delta$, BaZr0.95Ga0.05O3-$delta$ and BaZr0.95Y0.05O3-$delta$ were fabricated by a solid-state reaction method and subsequent sintering at 150$0^{circ}C$ to 1$600^{circ}C$ The microstructures and electrical characteristics of the specimens were studied. Only BaZr0.95Ga0.05O3-$delta$ showed dense microstructure and had typical impedance spectra at various temperature. Its electrical conductivity by impedance analysis was 2.7$ imes$10-3$Omega$-1.cm-1 at 90$0^{circ}C$ in air. The BaZr0.95Ga0.05O3-$delta$ exhibited lower grain rsistance in wet atmosphere than in dry atmosphere and the reduction of resistance is due to the proton conduction.
