    Abstract: 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. The heated gas is used to mechanically drive the power recovery turbine which is coupled to a generator to produce electrical energy.

    Abstract: The space heating system with fuel cells (11) has a connection to a public electrical network (50). In this system a fuel (B) can be supplied to the fuel cells in gaseous form through a main gas valve (200) for the production of thermal and electrical energy. The main gas valve has a control which, on an interruption of the current supplied, results in an automatic operating shutdown. The possibilities exist for the system to feed the electrical energy at least partly into the network and to deliver the thermal energy to a heating circuit which is operable with electrical energy from the network. An electrical inverter (4), with which direct current of the fuel cells can be converted into alternating current, can be operated in two operating states, on the one hand, for a feed into the public network, and, on the other hand, for a feed into the island network of the system. Means are provided with respect to a power cut of the public network by which a short-term maintenance of necessary functions of the space heating systemnullthe fuel supply into the fuel cells having first prioritynullis ensured without support by, for example, galvanic batteries. Moreover, controls and circuits are provided with which at least the necessary functions of the space heating system can continue to be maintained by means of electrical energy from the fuel cells.
