FUEL CELL SYSTEM AND ITS OPERATION METHOD

摘要

A fuel cell system includes: a fuel cell which generates electricity; and control means which supplies an output power from the fuel cell to a predetermined load power source while realizing a low-efficiency operation of the fuel cell, thereby driving and controlling the load power source. The control means sets the output voltage of the fuel cell during the low-efficiency operation to a value not smaller than the minimum drive voltage of the load power source.
