FUEL CELL SYSTEM

摘要

PURPOSE: A fuel cell system is provided to maintain stable operation even during the pressure reduction or the disruption of air supply to a valve. CONSTITUTION: A fuel cell system (100) comprises an air supply device (110) which is formed to supply compressed air into a compressed air distributor (140); and a gas supply device (120) which supplies gas into a fuel cell stack (130) and is being connected to the air supply device to supply the gas into the compressed air distributor when the pressure of the compressed air is a preset standard value or less. When the pressure of the compressed air is higher than the pressure of the gas, the compressed air flows into the compressed air distributor, forms a pressure of the standard value or more, and restricts the inflow of the gas into the compressed air distributor.
