Title:
燃料電池発電装置内等の水素処理搬送流からの汚染物質の除去方法及び装置
Document Type and Number:
Japanese Patent JP2007503106
Kind Code:
A
Abstract:
Method and apparatus are provided for removing contaminants from a hydrogen processor feed stream, as in a fuel cell power plant ( 110 ). Inlet oxidant ( 38 ), typically air, required by a catalytic hydrogen processor ( 34 ) in a fuel processor ( 14 ) for a fuel cell stack assembly ( 12 ) in the power plant ( 110 ), may contain contaminants such as SO2 and the like. A cleansing arrangement, which includes an accumulator/degasifier ( 142, 46 ) acting as a scrubber, and possibly also a water transfer device ( 118 ), receives the inlet oxidant and provides the desired cleansing of contaminants. Water in the water transfer device and in the accumulator/degasifier serves to dissolve the water-soluble contaminants and cleanse them from the oxidant stream. The cleansed oxidant stream ( 138 ') is then delivered to the hydrogen processor and to the fuel cell assembly, with minimal inclusion of detrimental contaminants such as sulfur.
