FUEL CELL SYSTEM AND HUMIDIFICATION DEVICE OF THE SAME

摘要

PURPOSE: A fuel cell system is provided to secure the durability of a fuel cell stack and stable output, by improving the absolute humidity of air supplied to a humidifier, and to improve the humidifying effectiveness. CONSTITUTION: A fuel cell system(100) comprises: a stack(10) consisting of aggregate of a fuel cell; an air supply unit for supplying air to an air electrode; a humidifier(50) humidifying air supplied from the air supply unit; and a hydrogen supply unit(70) for supplying hydrogen to the fuel electrode of the fuel cell. A humidifier comprises a first outlet for supplying humidified air to the air electrode, and a second outlet for exhausting the exhausted air to atmosphere. The second outlet is connected to the front end of the air supply unit through a bypass line(58).
