Abstract
A hydrogen purifier () includes: a shift conversion catalyst () which reduces, through a shift reaction, carbon monoxide contained in a hydrogen-containing gas; and a methanation catalyst () which reduces, through a methanation reaction, carbon monoxide contained in the hydrogen-containing gas that has passed through the shift conversion catalyst (). The shift conversion catalyst () and the methanation catalyst () are heat exchangeable with each other via a first partition wall (), and a flow direction of the hydrogen-containing gas that passes through the shift conversion catalyst () is opposite to a flow direction of the hydrogen-containing gas that passes through the methanation catalyst ().
