20100068580 | FUEL CELL SYSTEM - Fluid control valves, such as a humidifying module bypass valve, an inlet shutoff valve, an outlet shutoff valve are opened and closed by the pressure of air flowing in a fluid flow path. The pressure of air flowing in the fluid flow path is regulated, based on a drive demand pressure emitted to drive the flow control valves, by the flow rate of air discharged from an air compressor, the degree of opening of a fuel cell bypass valve, the degree of opening of an air pressure regulation valve, etc. The drive demand pressure for driving a shutoff valve is set such that, for example, the greater the absolute value of the negative pressure inside the fuel cell stack, the higher the drive demand pressure, and the air pressure is controlled to be the drive demand pressure. Since the pressure of air flowing in the fluid flow path is regulated based on a drive demand pressure of the fluid control valves, the response of drive and reliability of the fluid control valves are better than those in the case where, for example, the pressure is regulated based on a request from a fuel cell. | 03-18-2010 |
