| Research Abstract |
Nobel proton-conducting oxide thin films were fabricated by simple anodizing technique for possible application as an solid electrolyte for intermediate-temperature fuel cells. The amorphous ZrO2-WO3-SiO2 films formed by anodizing revealed the proton conductivity sufficient for the fuel cell application at ~200oC. In addition, the oxide films showed unique thickness-dependent conductivity with theconductivity highly enhanced by reducing the film thickness less than 300 nm.
