Title:
CO除去装置とこれを用いた燃料電池発電装置
Document Type and Number:
Japanese Patent JP4682403
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a CO removing apparatus and a fuel cells generating apparatus using it in which a CO concentration in a fuel gas can be reduced to a ppm level (e.g. several ten ppm), the amount of an expensive noble metal is small in use, a structure is simple and compacting the same can be made. SOLUTION: The CO removing apparatus 10 is provided with a fuel gas chamber 14 and a permeation chamber 16 which are divided by a hydrogen separation membrane complex 12. The hydrogen separation membrane complex 12 is comprised of a metal porous plate 12 which is supported so as to keep a pressure difference between the fuel gas chamber and the permeation chamber, a sintered metal plate 12b which is laminated with adhering closely to the fuel gas chamber side of the metal porous plate and a hydrogen separation membrane 11 which is coated on a surface of the sintered metal plate. A CO shift catalyst 17a is filled up in the fuel gas chamber 14, a fuel gas, which contains carbon monoxide, is supplied by a higher pressure than the permeation chamber and a methanation catalyst 17b is filled up in the permeation chamber 16.
