Patent ID: 8071245

Claim:
A hybrid fuel cell system, comprising: a fuel cell; an electric power storage device; a load portion which consumes electric power; and a control portion that is programmed to: compute a supply electric power set value, which is an amount of electric power that needs to be supplied from the electric power storage device; measure an actual supply electric power value indicating an amount of electric power that is actually supplied from the electric power storage device; determine whether the supply electric power set value is greater than or less than the actual supply electric power value; and change an amount of electric power consumed by the load portion to increase or decrease consumption after the control portion determines that the supply electric power set value is greater than or less than the actual supply electric power value; wherein the control portion is programmed to change the amount of electric power consumed by the load portion to increase or decrease consumption to remove imbalance between charge and discharge of the electric power storage device in the system by reducing a difference between the supply electric power set value and the actual supply electric power value.
