Abstract: An integrated hydrogen-electric includes a hydrogen fuel cell; a hydrogen fuel source; an electric motor assembly disposed in electrical communication with the fuel cell; n air compressor system configured to be driven by the motor assembly, and a cooling system having a heat exchanger radiator in a duct of the cooling system, and configured to direct an air stream including an air stream from the air compressor through the radiator, wherein an exhaust stream from a cathode side of the fuel cell is fed via an flow control nozzle into the air stream in the cooling duct downstream of the radiator.

Abstract: A fuel cell system is disclosed comprising a housing having an interior space fluidly containing a fuel cell stack and a flame arresting recombiner, wherein: (1) the flame arresting recombiner comprises at least one fuel cell having at least one anode supply channel fluidly connecting the fuel cell and the interior space of the housing; and (2) the anode supply channel of the fuel cell of the flame arresting recombiner is configured to prevent flame propagation.
