Abstract: A hydrogen generating apparatus comprising a reformer, a heating section, a fuel supply section, a water supply section, a shift reactor with a shift catalyst layer, a first heat exchanger on the downstream side of the shift catalyst layer, and a temperature detector for the shift catalyst layer. The temperature of the downstream portion of the shift catalyst layer is raised by the action of the heat exchanger compared with the temperature of the same before the amount of the reformed gas is increased. And, the temperature of the downstream portion is lowered compared with the temperature of the same before the amount of the reformed gas is reduced when reducing the amount of the reformed gas. Accordingly, regardless whether the generation amount of hydrogen is large or small, the hydrogen generating apparatus can supply a constant concentration hydrogen gas while keeping the concentration of byproduct carbon monoxide low.
