Embodiment Construction
[0048] The fuel cell system used in the present invention has a reformer for reforming hydrocarbon-based fuel to produce hydrogen-containing gas and a high-temperature fuel cell. The reformer has a reforming catalyst layer. High-temperature fuel cells use the hydrogen-containing gas obtained from the reformer to generate electricity. The reforming catalyst layer is composed of a reforming catalyst that promotes a reforming reaction. The hydrogen-containing gas obtained from the reformer is called reformed gas.
[0049] (Process a)
[0050] When the fuel cell system is actually started, step a is performed. That is, the temperature of the reforming catalyst layer is raised while measuring the temperature of the reforming catalyst layer. The temperature measurement and temperature rise in step a are continued until the start-up is completed.
[0051] As a heat source for this temperature increase, for example, an electric heater provided in a reformer can be used.
