Abstract Yttria stabilized zirconia (YSZ) powders comprised of Y/Zr in molar ratios of 0.01, 0.04, and 0.08, were prepared by a sol–gel method and their crystal structures and pore size distributions were determined. The 8‐mol% Y‐doped zirconia (8YSZ) powder restrained the crystallization and had the smallest pores. Porous 8YSZ membranes, prepared on a porous α‐alumina support tube by a sol–gel method, showed a low permselectivity of 5.1 for H2 to CO2. The membranes were modified by impregnation with Pt or Ni to improve the H2 permselectivity. The permselectivities of H2 to CO2 at 500°C through the Pt–YSZ and Ni–YSZ membranes were increased to 22 and 29, respectively.
