FUEL CELL MEMBRANE HUMIDIFIER AND FUEL CELL SYSTEM COMPRISING SAME

WIPO Patent Application WO/2022/164139

A1

The present invention relates to a fuel cell membrane humidifier capable of improving humidification efficiency by performing two-stage humidification, and a fuel cell system comprising same. A fuel cell membrane humidifier according to an embodiment of the present invention comprises: a dry air supply means; a fuel cell membrane humidifier which performs two-stage humidification on the dry air supplied from the dry air supply means; a fuel cell stack for generating energy and humid exhaust gas by reacting the humidified air supplied from the fuel cell membrane humidifier with hydrogen; and a bypass flow path for bypassing a portion of the exhaust gas generated in the fuel cell stack. The fuel cell membrane humidifier comprises: a mid-case; a cap which is fastened with the mid-case and has a bypass inlet connected to the bypass flow path; a mixing humidifier which performs mixed humidification by mixing the dry air introduced through the cap and the exhaust gas introduced through the bypass inlet; and at least one cartridge which is disposed in the mid-case and accommodates a plurality of hollow fiber membranes that perform moisture exchange.
