HUMIDIFIER FOR FUEL CELL

摘要

Disclosed is a humidifier for fuel cell which is capable of realizing high humidifying efficiency owing to the maximum contact area of hollow fiber membranes with reaction gas to be supplied to the fuel cell by enabling the uniform humidifying level in all the hollow fiber membranes provided inside the humidifier. The humidifier comprises 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 to uniformly distribute the moisture-containing unreacted gas supplied through the inlet to the plural holes.
