HYDROGEN GENERATING DEVICE AND FUEL CELL SYSTEM

摘要

A hydrogen generator includes: a hydro-desulfurizer configured to remove a sulfur compound in a raw material and including a tubular first wall; a reformer configured to generate a hydrogen-containing gas by using the raw material supplied from the hydro-desulfurizer; a tubular second wall provided coaxially with the first wall so as to be opposed to the first wall; and an electric heater annularly provided in a gap between the first wall and the second wall so as to turn back in the axial direction of the first wall and including a portion extending in an axial direction of the first wall.
