Claim 5:
6. A method for cooling a fuel cell aboard a fuel cell powered airplane, wherein the airplane includes an integrated hydrogen-electric engine including:
a hydrogen fuel cell;
an air inlet coupled to a cooling duct integrated into the aircraft, and
a cooling system having a radiator in the cooling duct, the steps of:
directing an air stream from the air inlet through the radiator, and
feeding an exhaust stream from a cathode side of the fuel cell into the cooling duct, wherein the exhaust stream is fed via a flow control nozzle into the air stream in the cooling duct both upstream and downstream of the radiator, wherein the cathode exhaust feed into the airstream in the cooling duct downstream of the radiator is introduced through a porous wall of the cooling duct.
