    摘要： A fuel cell system and a control method therefor are capable of improving power generation efficiency of the fuel cell more reliably during a normal operation. A fuel cell system is arranged along a vehicle frame of a motorcycle. The fuel cell system includes a fuel cell having a cathode, an air pump which supplies the cathode with oxygen-containing air, and a CPU which controls operation of elements which constitute the fuel cell system. The CPU determines, depending on situations, whether or not to perform an oxygen-starving process which is a process of starving the cathode of the oxidizer during the normal operation, and stops the air pump when a determination is made to perform the oxygen-starving process.

    摘要： A fuel cell system preferably includes a fuel cell which generates electric energy by electrochemical reaction, an aqueous solution tank which holds the methanol aqueous solution, a water tank which holds fluid discharged from the fuel cell, a fluid level sensor for detecting an amount of fluid in the water tank, a water pump which recycles fluid in the water tank to the aqueous solution tank, and a CPU which controls components of the fuel cell system. After power generation is finished, the water pump is driven to recycle all the fluid in the water tank to the aqueous solution tank. Further, after power generation is finished or before power generation is started, the fluid level sensor detects the amount of fluid in the water tank. If the amount of fluid is not smaller than a predetermined amount, the water pump is driven to recycle fluid in the water tank to the aqueous solution tank. The fuel cell system has a simple construction and is capable of preventing fluid from being discharged outside.

    摘要： A fuel cell system is capable of easily detecting an abnormality in an aqueous solution container, a circulation unit or a liquid level adjusting unit. The fuel cell system includes an aqueous solution tank which holds aqueous methanol solution; a level sensor which outputs one of detection signals HIGH and LOW in accordance with the liquid level in the aqueous solution tank; an aqueous solution pump for circularly supplying aqueous methanol solution to a cell stack; a water pump for supplying water to the aqueous solution tank; and a CPU which controls operation of the fuel cell system. The CPU detects that an abnormality exists based on comparison between a first predetermined time and a required time (LOW time) which is a time required for a detection signal to be changed from LOW to HIGH, or on comparison between a second predetermined time and a required time (HIGH time) which is a time required for the detection signal to be changed from HIGH to LOW.

    摘要： A fuel cell system is capable of determining abnormalities in an aqueous solution supply without providing new sensors for abnormality detection. A fuel cell system includes a cell stack, and an aqueous solution supply arranged to supply the cell stack with aqueous methanol solution. The aqueous solution supply is capable of making circulatory supply of aqueous methanol solution to the cell stack, and includes a main flow channel connected with a cell stack; a sub flow channel branched off the main flow channel and connected with a gas source; an aqueous solution tank which holds aqueous methanol solution; and an aqueous solution pump. An ultrasonic sensor is provided in the sub flow channel. The ultrasonic sensor is located at a place higher than a liquid level in the aqueous solution tank when the aqueous solution pump is stopped. Abnormalities in the aqueous solution supply are determined based on a result of concentration information detection from the ultrasonic sensor. The determination may also be based on a result of liquid amount detection in the aqueous solution tank.
