FUEL CELL SYSTEM

摘要

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.
