Abstract:
1. A fire protection system for reducing a fire danger in a room, the fire protection system comprising: a fuel cell for producing a nitrogen-enriched cathode exhaust air; a conduit system for supplying the nitrogen-enriched cathode exhaust air into the room, so that an oxygen content in the room is reduced, such that a fire danger in the room lowers; a first measurement unit for measuring a physical parameter, selected from the group consisting of the oxygen content of the exhaust air in the conduit system, and the hydrogen content of the exhaust air in the conduit system; a bleed valve in the conduit system; and a control unit for adjusting the oxygen content within the room by operating the bleed valve for releasing the cathode exhaust air into an environment of the fuel cell and not into the room.
