Hydrogen purifier, hydrogen generation apparatus, and fuel cell system

摘要

A hydrogen purifier includes: a CO remover configured to reduce carbon monoxide in a hydrogen-containing gas through an oxidation reaction, the hydrogen-containing gas containing ammonia and carbon monoxide; and an ammonia remover provided upstream from the CO remover, the ammonia remover being configured to cause a reaction between ammonia in the hydrogen-containing gas and oxygen by using a catalyst to decompose the ammonia.

主权项

1. A hydrogen purifier comprising:
a CO remover that reduces carbon monoxide in a hydrogen-containing gas through an oxidation reaction, the hydrogen-containing gas containing ammonia and carbon monoxide; an ammonia remover provided upstream from the CO remover and that causes a reaction between ammonia in the hydrogen-containing gas and oxygen by using a catalyst to decompose the ammonia; an oxygen-containing gas supply device; a first passage, through which an oxygen-containing gas from the oxygen-containing gas supply device is supplied to the ammonia remover; and a second passage, through which the oxygen-containing gas is supplied to the CO remover.
