摘要： A fuel cell system includes a cell stack, a temperature sensor which detects a temperature of the cell stack, an outside air temperature sensor which detects an outside air temperature, and a CPU which controls a process in the fuel cell system. When the temperature of the cell stack is lower than a predetermined temperature, the fuel cell system performs a temperature raising operation of the cell stack by making the concentration of aqueous methanol solution in an aqueous solution tank higher than in a normal operation and by making an output of an aqueous solution pump greater than in the normal operation. The CPU sets a run time for the temperature raising operation based on a detection result from the outside air temperature sensor, a detection result from the temperature sensor, and a run time setting table which is stored in a memory. The fuel cell system is capable of raising a temperature of the fuel cell quickly and stably to the predetermined temperature.

摘要： A fuel cell device has a small and compact structure as a whole. The fuel cell device employs a fuel cell (e.g., direct methanol fuel cell of an MEA structure) using liquid fuel. Diluted liquid fuel is prepared by diluting the liquid fuel (methanol-contained liquid in the case of DMFC) with dilution liquid, and is supplied to the fuel cell. A first pump unit stacked on the fuel cell supplies the diluted liquid fuel to the fuel cell while diluting the liquid fuel by mixing the liquid fuel and the dilution liquid together. A second pump unit stacked on the fuel cell collects liquid (water usable as dilution liquid in DMFC) produced by an electrochemical reaction in the fuel cell.
