摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system suppressing decrease in deterioration suppressing effect at staring of a fuel cell system and preventing unnecessary increase in starting time.
SOLUTION: The fuel cell system takes out current by operating a current taking out part 30 at system stop and closes an air line inlet valve 23 and an air line outlet valve 24. Since both valves 23, 24 are closed after start of current taking out, the oxidant electrode side is regulated after oxygen on the oxidant electrode side is consumed in a low oxygen state. Since regulation is conducted with both valves 23, 24, flowing in of outside air is regulated, and a low oxygen state is kept even at system starting.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of containing reduction of deterioration suppression effect at the time of starting of a fuel cell system and capable of preventing the starting time and the stopping time from becoming unnecessarily long.
SOLUTION: The fuel cell system extracts electric current by operating a current extraction part 30 and closes an air system inlet valve 23 and an air system outlet valve 24 at the time of system stop. In particular, since the current is extracted after the air system inlet valve 23 and the air system outlet valve 24 are closed, the consumption of oxygen of the oxidizer electrode side can be made less compared with the case the current is extracted before these valves 23, 24 are closed, and shortening of the time required for the stopping process can be realized. Furthermore, since the oxidizer electrode side is regulated by the both valves 23, 24, the state of low oxygen by consumption of oxygen at the time of stopping the system can be maintained even at the starting time.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell cooling system capable of suppressing deterioration of operation efficiency of a fuel cell, while supplying the fuel cell with flow rate required for cooling the fuel cell.
SOLUTION: The fuel cell cooling system 1 is provided with a cooling liquid flow-rate determination part 50. The cooling liquid flow-rate determination part 50 obtains a voltage drop amount by deducting the output voltage value of the fuel cell 10 from a reference voltage value. Also the flow-rate determination part 50 inputs information of a target extraction current value of the fuel cell 10. Then the flow-rate determination part determines a circulation flow-rate of the cooling liquid that is circulated in the cooling liquid circulation system 20, based on the voltage drop amount and the target extraction current value. Here, heat generation amount of the fuel cell 10 can be estimated, based on a product of the voltage drop amount and the target extraction current value. Accordingly, since the circulation flow-rate of the cooling liquid can be determined by the voltage drop amount and the target extraction current value, appropriate circulation flow-rate of the cooling liquid can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell system capable of controlling an air flow without giving a driver an uncomfortable feeling.
SOLUTION: In the fuel cell system equipped with a fuel cell bypass channel for oxidant gas, a target value of an air flow supplied to a fuel cell is set in switching over an air flow obtained from a current demand of the fuel cell and that obtained from the other request. When an acceleration/deceleration determination means 101 determines an acceleration state, a preceding target value of an air flow volume and that at present is compared, and if the target value of the air flow volume at present is smaller than at a previous time, the air flow is controlled with the previous air flow target value as the present air flow target volume.
