Abstract
An aircraft propulsion system includes a gas turbine engine, a water-exhaust heat exchanger, and a fuel cell segment. The gas turbine engine has a compressor, a combustor, and a turbine. The engine is in drive communication with a rotational load component. The water-exhaust heat exchanger is disposed to receive exhaust gas exiting the turbine section. The fuel cell segment includes a liquid hydrogen evaporator, a fuel cell, and a water pump. The liquid hydrogen evaporator is configured to change a flow of liquid hydrogen to a flow of gaseous hydrogen. The fuel cell is configured to receive a flow of air and the flow of gaseous hydrogen and react them to produce electrical power and a flow of water. The flow of water from the fuel cell goes to the water-exhaust heat exchanger which converts the flow of water to a flow of steam.
