Abstract

A hydrogen producing apparatus comprising: a reforming section having a reforming catalyst which causes a reaction between a carbon-containing organic compound as a feedstock and water; a feedstock supply section for supplying the feedstock to the reforming section; a water supply section for supplying water to the reforming section; a heating section for heating the reforming catalyst; a shifting section having a shift catalyst which causes a shift reaction between carbon monoxide and water contained in a reformed gas supplied from the reforming section; and a purifying section having a purifying catalyst which causes oxidation or methanation of carbon monoxide contained in a gas supplied from the shifting section, wherein the shift catalyst comprises a platinum group metal and a metal oxide.
