Catalyst for low temperature fuel cell using carbon nanofiber as a support, Electrode for low temperature fuel cell using the catalyst, and Low temperature fuel cell using the catalyst

摘要

A catalyst for a low temperature fuel cell is provided to maximize the efficiency while increasing the surface area of the dipped platinum catalyst, and to reduce noble metals. A catalyst for a low temperature fuel cell comprises a support and a catalyst. The support is fiber-like nano carbon of highly effective surface area, having the specific surface area measured with a nitrogen BET method of 100 m^2/g or more. The fiber-like nano carbon of highly effective surface area comprises the steps of: (i) manufacturing a transition metal alloy catalyst containing (a) iron single catalyst through oxidation reaction and reduction reaction and (b) at least one metal elected from the group consisting of nickel, cobalt, copper, and molybdenum; (ii) adding hydrogen gas to the catalyst, and performing reduction reaction to produce minute metals on the surface of the catalyst; and (iii) adding C1-4 saturated and unsaturated gas or the mixed gas consisting of carbon monoxide and hydrogen gas and heat-treating them.
