<P>PROBLEM TO BE SOLVED: To provide a humidifier for a fuel cell equipped with a heating means by which the possessed heat of the cooling water of the fuel cell can be used effectively for heating of a hollow yarn membrane so that the moisture in the hollow fiber film may not freeze in a cold district and the like. <P>SOLUTION: The humidifier 2 for fuel cells is constituted by accommodating a large number of water permeating hollow yarn membranes allotted along the length direction of a housing 31 in the above housing 31, and by performing moisture exchange between the above gases by making the gases, of which the moisture contents differ on the inside and outside of the hollow yarn films, respectively, pass through, to humidify the dry gas of lower moisture content. It has a heating means, which can supply quantity of heat to the hollow yarn membrane bunch 36 which has been bundled the hollow yarn membranes, and the cooling water (warm water) after cooling the fuel cell body is used as a source of heating the heating means. <P>COPYRIGHT: (C)2003,JPO |
