Thin or thick films of YSZ were fabricated by plasma spraying, slip casting, slurry coating, spray pyrolysis, and RF-ion plating methods. A porous electrode substrate of Ni/YSZ cermet anode or La0.06Sr0.4MnO3 cathode was used as a support for YSZ film fabrication. Current-voltage characteristic of hydrogen-oxygen fuel cell with a slurry coated or a slip casted YSZ film was excellent, because these films were dense. The plasma spraying method was most suitable for quick fabrication of cell stacks.
