Disclosed is a humidifier for a fuel cell having an enhanced humidifying performance and being able to prevent an instantaneous decrease of the output of a car which might occur at the time of high-speed driving. The humidifier comprises a membrane housing with first and second ends; a bundle of hollow fiber membranes provided in an inner space of the membrane housing; a humidity retainer provided in the inner space of the membrane housing; a first cover mounted on the first end of the membrane housing, the first cover including an inlet for introducing unreacted gas of high-humidity discharged from a stack; and a second cover mounted on the second end of the membrane housing, the second cover including an outlet for discharging the unreacted gas used for humidification.

Humidifier for fuel cell

Disclosed is a humidifier for fuel cell including a membrane housing including a first end, a second end positioned at an opposite side of the first end, and plural holes provided along the outer circumferential surface of the second end; hollow fiber membranes having both ends respectively potted into the first and second ends of the membrane housing, wherein the hollow fiber membranes are positioned inside the membrane housing; and a cap including an inlet for moisture-containing unreacted gas, wherein the cap is installed at the second end of the membrane housing, and an inner surface of the cap is provided with plural projections enabling the moisture-containing unreacted gas supplied through the inlet to be uniformly distributed to the plural holes.

The present disclosure relates to a polymer electrolyte membrane having a construction wherein an ionomer is charged in pores of a nanoweb having a high melting point, being insoluble in an organic solvent and having excellent pore characteristics, under optimum conditions. Therefore, an overall thickness of the electrolyte membrane may be reduced, thereby attaining advantages such as decrease in ohmic loss, reduction of material costs, excellent heat resistance, low thickness expansion rate which in turn prevents proton conductivity from being deteriorated over a long term. The polymer electrolyte membrane of the present invention comprises a porous nanoweb having a melting point of 300&#x25a1; or more and being insoluble in an organic solvent of NMP, DMF, DMA, or DMSO at room temperature; and an ionomer which is charged in pores of the porous nanoweb and contains a hydrocarbon material soluble in the organic solvent at room temperature.
