HYDROGEN GENERATOR, FUEL CELL SYSTEM, AND METHOD OF OPERATING HYDROGEN GENERATOR

摘要

A hydrogen generator (100) comprising: a raw-material feeder (4) which feeds a raw material containing a sulfur ingredient; a hydrogen feeder (7) which electrolyzes water to generate hydrogen; a hydrodesulfurizer (5) which removes the sulfur ingredient from the raw material fed by the raw-material feeder (4), using the hydrogen generated by the hydrogen feeder (7); and a reformer (1) in which the raw material from which the sulfur ingredient has been removed by the hydrodesulfurizer (5) is subjected to a reforming reaction to yield a hydrogen-containing gas.
