FUEL CELL SYSTEM AND CHARGING DEVICE

PROBLEM TO BE SOLVED: To provide a fuel cell system for achieving consistently stable operation by stably charging the battery element of an internal power supply, and to provide a charging device. SOLUTION: The fuel cell system includes a fuel cell body 1 for generating power with the supply of fuel and supplying the generating output to electronic equipment 7, and a LIB 5 used as the internal power supply to be charged by the generating output of the fuel cell body 1. Depending on the magnitude of required output acquired by a load requirement detecting part 6 for detecting output which the electronic equipment 7 requires for the fuel cell body 1, a charging condition selecting part 81 selects the rate of the generating output to be supplied to the LIB 5 to the generating output of the fuel cell body 1 as the charging condition of the LIB 5. Depending on the selected charging condition, the predetermined generating output out of the generating output of the fuel cell body 1 is supplied as charging output for the LIB 5.
