Abstract
A hydrogen generator includes: a tubular reformer configured to generate a hydrogen-containing gas by a reforming reaction using a material gas; a CO reducer configured to reduce carbon monoxide contained in the hydrogen-containing gas generated in the reformer; a tubular hydro-desulfurizer provided at an outer periphery of the reformer and configured to remove a sulfur compound contained in the material gas; and a material gas supply passage through which the material gas to be supplied to the hydro-desulfurizer flows. The material gas supply passage is configured to perform heat exchange with the CO reducer, and a material gas inlet port of the hydro-desulfurizer is provided at an end surface closer to the CO reducer.

A hydrogen generator comprising:
- a tubular reformer configured to generate a hydrogen-containing gas by a reforming reaction using a material gas;
- a CO reducer configured to reduce carbon monoxide contained in the hydrogen-containing gas generated in the reformer;
- a tubular hydro-desulfurizer provided at an outer periphery of the reformer and configured to remove a sulfur compound contained in the material gas;
- and
- a material gas supply passage through which the material gas and the hydrogen-containing gas to be supplied to the hydro-desulfurizer flows, wherein an output of the reformer is fluidly coupled to the material gas supply passage, wherein:
- the material gas supply passage is configured to perform heat exchange with the CO reducer;
- the hydro-desulfurizer has one end surface and another end surface;
- and
- a material gas inlet port of the hydro-desulfurizer is provided at the one end surface closer to the CO reducer than the another end surface.
