A fuel cell system to rapidly increase the temperature of unit cells. The fuel cell system includes; a plurality of current generating unit cells; a load circuit to supply the current to a load; a short circuit to connect the cells to an electrically closed loop without passing through the load; a thermo sensor to measure the temperature of the cells, and a controller that controls the delivery of the current to the load circuit and the short circuit, according to the temperature measured by the thermo sensor. The fuel cell system can rapidly increase the temperature of the unit cells when the temperature of the unit cells is below an operating temperature, thereby reducing the time required for the fuel cell to generate a stable output voltage.

A liquid fuel mixing apparatus includes a water chamber, a fuel chamber, and a partition arranged substantially vertically between the water chamber and the fuel chamber. The partition includes a passage to permit communication between the water chamber and the fuel chamber. The water chamber includes a first port for the inflow of water and air recovered from a cathode of the fuel cell. The fuel chamber includes a third port for the inflow of unreacted fuel and CO2 from an anode of the fuel cell, a fourth port for the inflow of a liquid fuel from a liquid fuel tank, and a fifth port for the outflow of a mixed fuel to the fuel cell.
