HUMIDIFIER APPARATUS FOR FUEL CELL

摘要

PURPOSE: A humidifier for fuel cell capable of controlling the moisture of hydrogen or oxygen supplied to a fuel cell stack by using the water of a liquid-gas separation part, thereby preventing an electrolyte membrane in the fuel cell stack, and increasing the efficiency of electricity generated in the fuel cell stack. CONSTITUTION: A humidifier for fuel cell comprises: a fuel cell stack(10) generating electricity through hydrogen and oxygen; a hydrogen feed part supplying the hydrogen to the fuel cell stack; an oxygen feed part supplying oxygen to the fuel cell stack; a gas-liquid separation part(40) separating steam in the hydrogen exhausted from the fuel cell stack; a first humidifying part supplying hydrogen, which is humidified by using condensed water separated from the gas-liquid separation part; and a second humidifying part supplying oxygen, which is humidified by using the condensed water separated from the gas-liquid separation part.
