Hydrogen generation apparatus and fuel cell system

摘要

A hydrogen generation apparatus has a reformer of generating a reformed gas containing at least hydrogen and carbon monoxide by making a material containing an organic compound react with water; carbon-monoxide-removing means of including at least a shifter of reducing the carbon monoxide contained in the reformed gas generated by the reformer in accordance with a shift reaction; and material-humidifying means of humidifying the material by directly or indirectly using moisture contained in the reformed gas.
