    Abstract: The present invention relates to a titanium suboxide support for a catalyst electrode for a fuel cell and to a low-temperature synthesis method of the titanium suboxide support. More specifically, the present invention relates to titanium suboxide (Ti_xO_2x-1) nanoparticles which are useful as a support for a catalyst electrode for a fuel cell; and to a method for synthesizing the titanium suboxide (Ti_xO_2x-1) nanoparticles at a low temperature of 600-900°C by using TiO_2, a Co catalyst and hydrogen gas. The titanium suboxide nanoparticles have the advantage of having excellent corrosion resistance to acid, high thermal conductivity and electrical conductivity, and excellent durability. Therefore, the catalyst electrode manufactured by using the titanium suboxide nanoparticles as a support shows high catalytic activity and enhanced oxidation-reduction properties through a fuel cell test.

    Abstract: PURPOSE: A catalyst electrode for a fuel cell is provided to improve catalyst activation and oxidation-reduction property due to high interaction with a catalyst through a fuel cell test by using titanium nitride as a supporter and to secure stability even in case of being operated in a long time. CONSTITUTION: A catalyst electrode for a fuel cell uses titanium nitride nitrided in titanium oxide through a thermal process as a supporter of a catalyst. A method for manufacturing the catalyst electrode for a fuel cell comprises the steps of: evenly spreading titanium oxide on a boat, putting the boat in an electric furnace, and flowing nitrogen gas to make a nitrogen atmosphere; flowing ammonia gas while raising the nitrogen atmosphere temperature to a preset temperature for a predetermined time; and nitriding the titanium oxide by maintaining the preset temperature for a predetermined time.
