Hydrogen generator, fuel cell system and their operating methods |
摘要 |
A hydrogen generator (4) includes: a reformer (5) which is supplied with a raw material to generate a hydrogen-containing gas through a reforming reaction; a first gas supplying unit (1) which supplies a gas containing a nitrogen-containing compound to the reformer; a CO remover (7) which has an oxidation catalyst containing a metal to be poisoned by ammonia and uses the oxidation catalyst and an oxidation gas to remove carbon monoxide in the hydrogen-containing gas through an oxidation; a second gas supplying unit (3) which supplies the oxidation gas to the CO remover; and a control unit (10), wherein the gas containing the nitrogen-containing compound is supplied from the first gas supplying unit to the reformer during the reforming reaction, a fuel cell system (100) includes the hydrogen generator (4), and the control unit is configured to control to carry out a regeneration operation of the oxidation catalyst if a parameter regarding a cumulative amount of ammonia supplied to the CO remover has reached a predetermined threshold or more. |
