HYDROGEN PRODUCTION APPARATUS AND FUEL CELL SYSTEM

摘要

A hydrogen production apparatus includes a preferential oxidation unit that preferentially oxidizes carbon monoxide in a reformed gas containing hydrogen, a vaporization flow path that passes water to generate steam, and a gas flow path through which the reformed gas passes. The gas flow path is arranged between the preferential oxidation unit and the vaporization flow path. The reformed gas passes through the gas flow path and thereafter flows into the preferential oxidation unit.
