Patent ID: 7045232

Claim:
A fuel-cell system, comprising: a reformer unit configured to produce hydrogen from a raw material and inflowing air; a fuel-cell unit disposed downstream of the reformer unit, fuel-cell unit being operable in accordance with the hydrogen produced by the reformer unit; an oxidation device configured to convert carbon monoxide into carbon dioxide, the oxidation device being located between the reformer unit and the fuel-cell unit; and a compressor, one stage of the compressor configured to supply air to the reformer unit and another stage of the compressor configured to supply air to the fuel-cell unit, wherein the compressor is configured to compress the air to first pressure and to further compress to a second pressure the air compressed to the first pressure, the compressor tapped at the first pressure to supply the air to the fuel-cell unit and tapped at the second pressure to supply the air to the reformer unit.
