Combined aircraft hybrid fuel cell auxiliary power unit and environmental control system and methods are disclosed. In one embodiment, an auxiliary power unit includes a fuel cell component which chemically converts combustible fuel into electrical energy. Unutilized fuel emitted by the fuel cell component is combusted by a burner to generate heated gas. The heated gas is received by and drives a turbine, which in turn drives a drive shaft. A compressor, coupled to the drive shaft, compresses a source of oxidizing gas for supplying compressed oxidizing g...
What is claimed is: 1. A system for providing electrical power and a breathable airflow into a compartment, comprising: a fuel cell component coupled to a fuel supply and to a first pressurized flow of air, the fuel cell component being configured to provide an electrical output and a combustible exhaust flow; a burner coupled to receive the exhaust flow from the fuel cell component and disconnected from the fuel supply, the burner being configured to provide a hot gas outflow; a turbine configured to be driven by the hot gas outflow from the burner; an...
