Abstract:
1. A carbon monoxide concentration reduction apparatus, comprising: a hydrogen-rich gas supply that supplies the hydrogen-rich gas; an oxygen supply that supplies oxygen used for oxidizing the carbon monoxide; a carbon monoxide selective oxidizing catalyst, comprising a carbon monoxide selective oxidizing reactor that includes the carbon monoxide selective oxidizing catalyst and receives a supply of the hydrogen-rich gas and the oxygen from the hydrogen-rich gas supply and the oxygen supply, respectively, to selectively oxidize carbon monoxide contained in the hydrogen-rich gas through the carbon monoxide selective oxidizing reaction, wherein the carbon monoxide concentration reduction apparatus oxidizes the carbon monoxide contained in the hydrogen-rich gas, thereby reducing a carbon monoxide concentration in the hydrogen-rich gas; the carrier consists of ferrierite; and the transition metal is at least one type of metal selected from the group consisting of cobalt (Co), manganese (Mn), chromium (Cr), and iridium (Ir).
