Combined aircraft hybrid fuel cell auxiliary power unit and environmental control system and methods are disclosed. In one embodiment, a method includes chemically converting a portion of combustible fuel into electrical energy. An unutilized portion of fuel emitted by the chemical conversion of combustible fuel is combusted to thermal power. The heated gas is used to drive a power recovery turbine connected to a drive shaft. A source of input oxidizing gas is compressed and is used to help chemically convert the combustible fuel into electrical energy. ...
What is claimed is: 1. A method of combining a fuel cell and a power recovery turbine to generate electrical power in an aircraft, the method comprising:chemically converting a portion of combustible fuel into electrical energy using the fuel cell coupled to a pressurized flow of air to generate direct current and alternating current;combusting an unutilized portion of fuel emitted by the chemical conversion of combustible fuel to electrical power to generate heated gas;using the heated gas to drive the power recovery turbine connected to a drive shaft;c...
