Abstract
A control method is provided for a fuel cell system including a solid oxide fuel cell stack that uses a hydrocarbon-based fuel as a fuel and that contains, at an anode, a reforming catalyst for reforming the fuel and an oxidation catalyst for oxidizing the fuel. The control method includes warming up the fuel cell system by a first warm-up phase and a second warm-up phase. In the first warm-up phase, heated air is circulated at least to a cathode to warm up the fuel cell system using heat of the heated air. In the second warm-up phase, after the first warm-up phase, a mixture of the fuel and air is introduced into the anode, the fuel is oxidized by the oxidation catalyst, and warm-up is performed using heat generated by an oxidation reaction of the fuel.
