Problems solved by technology

When the flame in the combustion burner disappears, the heat required for the reforming reaction cannot be provided to the reformer, so hydrogen cannot be generated in the reformer
Therefore, it is no longer possible to use fuel cells to generate electricity and heat

Abstract

A hydrogen generation device (100) comprises a hydrogen generator (1) which generates fuel gas by reforming reaction using raw fuel, a combustor (2) which heats the hydrogen generator (1), an on / off valve (8A) which interconnects / interrupts a gas channel (8) through which the gas fed from the hydrogen generator (1) is supplied to the combustor (2), a combustion air supply unit (4) which supplies combustion air to the combustor (2), an ignition device (5) provided in the combustor (2), and a controller (30). When the combustor (2) misfires during generation of hydrogen-containing gas in the startup process, the controller (30) carries out ignition operation of the ignition device (5) while maintaining the open state of the on / off valve (8A).

Description

technical field [0001] The present invention relates to a hydrogen generator and a fuel cell system including the hydrogen generator. In particular, the present invention relates to a raw material and steam using organic compounds containing carbon and hydrogen as structural elements such as natural gas, LPG (Liquefied Petroleum Gas: liquefied petroleum gas), gasoline, naphtha, kerosene, methanol, etc. A hydrogen generator for generating hydrogen-containing gas through a reforming reaction, and a fuel cell system including the hydrogen generator. Background technique [0002] Conventionally, in a hydrogen generator for supplying hydrogen, a raw material containing an organic compound having carbon and hydrogen as structural elements is steam-reformed in a reformer equipped with a reforming catalyst layer. Through this reforming reaction, a hydrogen-containing gas containing hydrogen (hereinafter simply referred to as "hydrogen gas" and sometimes simply referred to as "fuel ...
