Abstract
A shift reactor for fuel cells, a fuel cell system employing the same, and an operating method of the same are provided. More particularly, a shift reactor for fuel cells is filled with a shift catalyst and includes an inlet through which reactants flow into the shift reactor and an outlet through which products flow out of the shift reactor. An oxygen supply duct and a valve capable of regulating the oxygen supply are positioned at the outlet side of the shift reactor. The oxygen supply allows for the temperature of the shift catalyst to be increased rapidly at startup, thereby significantly shortening the startup time of the shift reactor and thereby contributing to an improved practical operation of the fuel cell system.
