FUEL CELL SYSTEM AND ITS OPERATION METHOD
Document Type and Number:
Japanese Patent JP2006310103
Kind Code:
A
Abstract:
To restrain degradation of a fuel cell due to gas supply delays.
The fuel cell system, with a hydrogen pressure control valve H9 fitted in a fuel supply channel 74 to supply hydrogen to the fuel cell through, is provided with a determining part 5b for determining the pressure control delay of the hydrogen pressure control valve H9, based on an output of a pressure sensor P9 measuring downstream pressure of the hydrogen pressure control valve H9. A control part 5a controls the upper limit of the output target value of the fuel cell 20, when the pressure control delay is determined as having occurred by the determining part 5a.
