Abstract
A fuel cell system includes at least one fuel cell unit which is accommodated in a fuel cell enclosure. A cathode gas delivery line, cold-start gas delivery line, a cathode off-gas return line, anode off-gas return line may also be provided. According to the invention, the system is equipped with at least one Coanda flow amplifier in order to amplify the air stream for the purpose of ventilating the fuel cell enclosure, a cathode gas stream, a cold-start gas stream, a recirculated cathode off-gas stream or a recirculated anode off-gas stream. The may be equipped with a ventilating means for a housing outside the fuel cell enclosure. In the housing are components of the fuel cell system, said ventilating means including a Coanda flow amplifier.
