Hydrogen generator and fuel cell system

Abstract

A hydrogen generator includes: a reformer configured to generate a hydrogen-containing gas by using a raw material; a hydro-desulfurizer configured to remove a sulfur compound in the raw material; a recycle passage through which the hydrogen-containing gas is supplied to the raw material before the raw material flows into the hydro-desulfurizer; a booster configured to supply the raw material to the reformer; a raw material supply passage through which the raw material to be supplied to the reformer flows; and an ejector which is disposed on the raw material supply passage provided downstream of the booster and upstream of the hydro-desulfurizer and into which the hydrogen-containing gas flows from the recycle passage.
