Abstract

A fuel cell system (100) according to the present invention includes: a hydrogen generator (1) configured to generate a fuel gas through a reforming reaction by using a raw fuel; a fuel cell (7) configured to generate power by using the fuel gas; a combustor (2) configured to heat the hydrogen generator (1); at least one on-off valve (9A, 9B) configured to open / block a gas passage (9) through which the gas that is sent out from the hydrogen generator (1) is supplied to the combustor (2); and a combustion air supply device (4) configured to supply combustion air to the combustor (2); an ignition device (5) provided at the combustor (2), and a controller (30). The combustor (2) is configured to perform combustion during power generation of the fuel cell (7) by using the gas supplied through the gas passage (9). In a case where accidental flame extinction has occurred at the combustor (2) during the power generation of the fuel cell (7), the controller (30) performs an ignition operation of the ignition device (5) with the on-off valve (9A, 9B) kept opened.

Description

technical field [0001] The present invention relates to fuel cell systems. In particular, the present invention relates to a fuel cell system for generating electricity using hydrogen-rich gas produced by steam reforming reactions using hydrocarbons such as natural gas, LPG, gasoline, naphtha, kerosene, and methanol as the main raw material (raw material fuel) . Background technique [0002] In the hydrogen generator of the fuel cell system, a raw material fuel containing an organic compound composed of carbon atoms and hydrogen atoms is steam-reformed in a reformer equipped with a reforming catalyst layer. A hydrogen-rich gas (hereinafter abbreviated as "hydrogen gas" and sometimes abbreviated as "fuel gas") is produced as a reformed gas by this reforming reaction. [0003] In the fuel cell of the fuel cell system, electricity and heat are generated by using the above-mentioned hydrogen gas and reacting the hydrogen gas with an oxidant gas such as air. [0004] Under amb...
