PURPOSE:To make it possible to compensate a transient fuel gas in a sudden increase of load and to increase the response speed of the power generation by providing a liquid fuel feeding device connected at the downstream side of the fuel processing device of a fuel system and to spray-inject the liquid fuel into the fuel gas when the load of the fuel cell main body is increased suddenly. CONSTITUTION:A liquid fuel feeding device connected to the downstream side of the fuel processing device of a fuel system and to spray-inject the liquid fuel into a fuel gas when the load of the fuel cell main body is increased suddenly is provided. A liquid fuel spray nozzle 20 to inject a pressured liquid fuel into the fuel gas (c) near the inlet of the anode 7 of a molten carbonate type fuel cell 6 is provided, for example. As a result, the liquid fuel of a low carbon number alcohol such as methanol injected directly in the fuel gas (c) at the inlet of the anode 7 of the fuel cell main body 6 is evaporated instantly. After that, the vapor is promoted to react with the steam included in the fuel gas (c) inside the cathode 7 by the catalystic function of the electrode material Ni and the like. The fuel which is short transiently can be compensated consequently, and the load of the molten carbonate type fuel cell can be increased instantly, consequently. |
