PURPOSE: A humidification system for a fuel cell is provided, to minimize the deterioration of the durability of a membrane electrode assembly and to improve the efficiency by suppressing the generation of water produced after reaction. CONSTITUTION: The humidification system comprises a reaction part inside a stack comprising a first reaction part and a second reaction part; an additional auxiliary inhalation manifold(60) for inhaling air into the stack; and an air circulation line(80) for flowing some air through a stack inhalation manifold(60) into the first reaction part. The circulated some air is reacted at the first reaction part to have high humidity, the air having high humidity is mixed with the rest air flown through the auxiliary inhalation manifold(60), and the mixed air is reacted at the second reaction part. Preferably the ratio of the air for first reaction is 20-85 %. |
