Abstract
A hydrogen generator () includes: a heater () which combusts a mixture gas of combustion fuel and combustion air to generate a combustion gas; a preheat evaporator () which heats a raw material and water by the combustion gas generated by the heater to generate a mixture gas of the raw material and the water; a reformer () which generates a hydrogen-containing gas by causing the mixture gas generated by the preheat evaporator to pass through a reforming catalyst () heated by the combustion gas; and a shift converter () which incorporates a shift catalyst () which reduces, by a shift reaction, carbon monoxide contained in the hydrogen-containing gas generated by the reformer, and further includes a water trapping portion () which traps liquid water discharged from the preheat evaporator, and the hydrogen generator () is configured to carry out heat exchange between the hydrogen-containing gas supplied from the reformer to the shift converter and the water in the water trapping portion.
