Abstract
A hydrogen generator includes: a reformer () configured to generate a hydrogen-containing gas by a reforming reaction using a raw material; a combustor () configured to heat the reformer; an air supplying device () configured to supply combustion air to the combustor; a first heat exchanger () configured to recover heat from a flue gas discharged from the combustor; a first heat medium passage () through which a first heat medium flows, the first heat medium receiving the heat recovered from the flue gas in the first heat exchanger; a first pump () configured to cause the first heat medium in the first heat medium passage to flow; a heat accumulator () configured to store the heat recovered by the first heat medium; and a controller () configured to cause the first pump to operate in a cooling step that is a step of cooling down at least the reformer by supplying the air from the air supplying device to the combustor in a state where the combustor is not carrying out combustion during a stop processing
