ABSTRACT:
An apparatus of removing carbon monoxide, has:a hydrogen gas supply unit of supplying a hydrogen gas,a catalytic reaction unit provided with a catalyst body carrying a platinum group metal catalyst,a hydrogen gas introducing unit which introduces a hydrogen gas containing carbon monoxide from the hydrogen gas supply unit to the catalytic reaction unit, andan oxidizing gas supply unit of supplying an oxidizing gas containing oxygen to the catalytic reaction unit,whereinthe catalyst body is brought into an oxidizing atmosphere for a period of time during operation according to a predetermined condition or when the apparatus is stopped. Thus, carbon monoxide can be eliminated sufficiently.
