摘要： PROBLEM TO BE SOLVED: To provide a starting method for a fuel cell system capable of promptly carrying out starting.
SOLUTION: The starting method is for the fuel cell system provided with a fuel cell 1 carrying out power generation by electrochemical reaction of gaseous hydrogen and gaseous oxygen in air, a gaseous hydrogen circulating passage 13 merging a gaseous oxygen discharge passage 16 connected to the fuel cell 1 to a gaseous hydrogen supply passage 12, and a purge valve 15 exhausting circulating gaseous hydrogen from the gaseous hydrogen circulating passage 13. It is characterized by that the gaseous hydrogen is supplied to the fuel cell 1, the purge valve 15 is opened, and after gaseous nitrogen of the gaseous hydrogen circulating passage 13 is replaced by the gaseous hydrogen, the purge valve 15 is closed.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell operating method capable of preventing freezing of a reaction gas passage, and minimizing energy necessary for drainage by draining water in a system only when it is necessary.
SOLUTION: In the operating method for a fuel cell 1, gaseous hydrogen and air are supplied as reaction gases to each reaction gas passage 5 and 6, and power generation is carried out by electrochemical reaction. It is characterized by that water in the reaction gas passages 5 and 6 are drained and operation of the fuel cell 1 is stopped by cutting off electric power supply from the fuel cell 1, detecting an outside air temperature, and supplying the reaction gases to the reaction gas passages 5 and 6 in response to the outside air temperature.

摘要： PROBLEM TO BE SOLVED: To provide a starting method of a fuel cell system which improves low-temperature start characteristics by properly controlling opening/closing of a purge valve.
SOLUTION: A fuel cell 1 generates power through electro-chemical reaction between hydrogen gas and air. A hydrogen gas circulation path 13 makes a hydrogen gas exhaust path 16 join to the fuel cell 1 and a hydrogen gas supply path 12 run together. A purge valve 15 discharges a circulating fuel gas from the hydrogen gas circulation path 13. The fuel cell 1 is supplied with the hydrogen gas and the air. If the temperature of the fuel cell 1 is below a prescribed temperature after the generated power is started to be supplied to an external electric load from the fuel cell 1, opening operation of the purge valve 15 is prohibited so that the hydrogen gas circulation path 13 is closed. If the temperature of the fuel cell 1 is equal to or above the prescribed temperature, opening operation of the purge valve 15 is permitted.

摘要： An air inlet is provided at the bottom of a vehicle to open downwardly. The air inlet is connected by a first tube to an air cooler for a PDU and a down converter. A fan for inputting the flow of air and turning its direction 90 degrees is connected at the downstream of the air cooler. The fan is further connected by a second tube to an exhaust outlet. The air inlet is located above a fuel tank thus to prevent any object jumping up from the road surface from straightforwardly entering the air inlet while the vehicle is running. The exhaust outlet is located above a silencer and can thus be prevented from being frozen in the winter. Using the above arrangement, the present invention embodies an air-intaking and exhausting apparatus in an air cooling system for air cooling the PDU and the down converter at higher efficiency without the help of the air cooler mounted in the interior of the vehicle.

摘要： PROBLEM TO BE SOLVED: To efficiently cool a PDU and a downverter by air without using an air conditioning device installed inside a body. SOLUTION: An inlet port 21 is downwardly provided in the rear bottom of a vehicle V, and a first pipe 22 connects the inlet port 21, a PDU and an air cooler 23 of a downverter. A fan 24, to which an exhaust port 26 is attached via a second pipe 25, is provided to the downstream air cooler 23 for air intake and 90 deg. directional change of air flow. The inlet port 21 is positioned above a fuel tank 17 so that objects on the road surface will not jump to hit the inlet port 21 squarely during travel of the vehicle V. The exhaust port 26 is positioned above a silencer 19 so as not to freeze in winter.
