Abstract: A method for controlling a catalytic combustion apparatus having a heater capable of heating fuel to be supplied to a catalyst includes a step of supplying oxidant gas to the catalytic combustion apparatus, and an injection step of injecting the fuel into the catalytic combustion apparatus. The injection step also includes an electric power feeding step of supplying electric power to the heater, and a setting step of setting an injection amount of the fuel to be injected into the catalytic combustion apparatus in response to output of the heater.

Abstract: A fuel cell system includes a collector configured to collect vaporized fuel that is vaporized in a fuel tank; an introduction path that is connected to the fuel tank and the collector, the introduction path being configured to guide the vaporized fuel to the collector; a discharge path configured to discharge the vaporized fuel collected by the collector to a supply/discharge mechanism; and a supply path and a purge gas supply unit that are connected to the collector, the supply path and the purge gas supply unit being configured to supply, to the collector, purge gas for pushing out the vaporized fuel collected by the collector into the discharge path.
