Thin film fabrication of stabilized zirconia for solid oxide fuel cells

Abstract

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 La 0.06 Sr 0.4 MnO 3 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.
