HYDROGEN GENERATOR, FUEL CELL SYSTEM EQUIPPED WITH THE SAME, AND METHOD FOR STARTING THE HYDROGEN GENERATOR

摘要

PPROBLEM TO BE SOLVED: To solve the problem that methanation violently proceeds and thermal runaway is occurred in a CO remover in the starting operation and it becomes impossible to stably start in some cases, in a hydrogen generator. PSOLUTION: The hydrogen generator comprises a reformer 1 for generating a hydrogen-containing gas from a raw material, a converter 2 for reducing carbon monoxide in the hydrogen-containing gas generated in the reformer 1 by a conversion reaction, and a CO remover 3 for reducing carbon monoxide in the hydrogen-containing gas passed through the converter 2 by an oxidation reaction, wherein the gas passed through the CO remover 3 can be heat exchanged with the converter 2.
