Title:
固体高分子型燃料電池のCO除去方法及び装置
Document Type and Number:
Japanese Patent JP5024717
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a CO removing method and device for solid polymer type fuel cell, capable of precisely maintaining a CO selective oxidization catalyst in a CO remover in a suitable temperature range, approximately 100 to 150 deg.C, without supercooling or superheating and is capable of achieving miniaturization by reducing the installation area for or device as a whole combined with a shift reactor. SOLUTION: Pressure in a cooling pipe 25a, passing through a catalyst layer 36a where the CO selective oxidization catalyst is filled, is controlled to be saturated vapor pressure in a temperature suitable for cooling the CO selective oxidization catalyst. Cooling water, preheated to a temperature suitable for cooling the CO selective oxidization catalyst, is supplied to the cooling pipe through applied pressure. Thus, the catalyst layer is cooled by vapor-liquid two-phase flow, flowing in the cooling pipe.
