Patent ID: 7833669

Claim:
A fuel cell system comprising: an energy supply comprising a fuel cell, a power distributor connected to the fuel cell, and a secondary cell connected to the fuel cell via the power distributor; a load set connected to the fuel cell and the secondary cell via the power distributor, the load set comprising auxiliary equipment for power generation of the fuel cell; and a controller configured to start a temperature rise promoting operation, when the fuel cell system is started up and if a warm-up mode is required, wherein the controller is configured to perform the temperature rise promoting operation by alternately repeatedly switching between a first power distribution unit and a second power distribution unit regardless of power consumption of the load set, for promoting concurrent temperature rise of both of the fuel cell and the secondary cell, wherein the first power distribution unit has a first power generated at the fuel cell and distributed to the secondary cell and the load set, and wherein the second power distribution unit has a combination of a second power generated at the fuel cell and a third power discharged from the secondary cell, distributed to the load set.
