FUEL CELL SYSTEM

摘要

It is possible to prevent excessive power generation of a fuel cell when a failure has occurred. When a start signal is inputted (Yes in step 102), a fuel cell system sets a release end voltage of the fuel cell as an initial value of the output voltage of the fuel cell corresponding to the output current zero of the fuel cell (step 103). When a failure is detected (Yes in step 104), the fuel cell system reads out the release end voltage preset as the initial value as an output voltage corresponding the output current zero and controls the voltage so that the output voltage of the fuel cell coincides with the release end voltage (step 107).
