Brennstoffzellensystem

摘要

There is disclosed a fuel cell system which can control an output current of a fuel cell even if an error occurs in split flow control of an oxidizing gas. The fuel cell system includes a fuel cell and a feed device for supplying the oxidizing gas under pressure to the fuel cell. A feed channel is connected to a discharge channel by a bypass channel so that the oxidizing gas flows while bypassing the fuel cell. The system includes a regulator valve and a bypass valve which adjust the split flow of the oxidizing gas to the bypass channel and the fuel cell. When the regulator valve or the bypass valve has an error, a controller stops the control of the output current of the fuel cell by control of the regulator valve and switches the control to a control of the output current of the fuel cell by control of the feed device.
