Abstract

A fuel cell system includes an evaporating portion (2), a reforming portion (3) forming an anode fluid, a fuel cell (1) generating an electric power, a tank (4), a water supply passage (8) connecting the tank and the evaporating portion and allowing water in the tank to be supplied to the evaporating portion, a water supply source (80) provided at the water supply passage to transmit the water in the tank to the evaporating portion, a stepping motor (82) driving the water supply source, and a control portion (100) driving the stepping motor to transmit the water in the tank to the evaporating portion. The control portion performs a harmful vibration restraining process to change a resonance frequency of the stepping motor by changing the number of steps per rotation of the stepping motor based on a volume of the water transmitted to the evaporating portion per time unit.
