Abstract
A method of controlling a fuel cell device includes: a step of supplying hydrogen to a hydrogen supply unit; a step of measuring a voltage between a fuel electrode and an oxidant electrode and determining whether the voltage is equal to or greater than a reference voltage; and a step of discharging a gas containing oxygen from the gas supply unit to the outside while supplying the gas to the gas supply unit when the voltage is equal to or greater than the reference voltage.
