Abstract

See full text

A fuel cell system is arranged to charge a secondary battery, which is detachable from the fuel cell system, and to supply electric power to a load. The fuel cell system includes a cell stack having a plurality of fuel cells and a controller having a CPU. During power generation in the cell stack, the CPU determines whether or not the secondary battery has been removed from the fuel cell system based on a voltage drop in the cell stack. With the determination that the secondary battery has been removed, the CPU turns off a relay and power supply from the cell stack to the load is stopped. The fuel cell system reliably maintains its operation even after removal of the secondary battery.
