Abstract
A power source for an aircraft including a solid oxide fuel cell and a proton exchange membrane fuel cell along with a solid oxide fuel cell multi-power source. At least one battery is electrically coupled to the solid oxide fuel cell, the proton exchange membrane fuel cell, and an aircraft distribution network to supply electricity to the aircraft and also for becoming recharged by the solid oxide fuel cell and the proton exchange membrane fuel cell.
Claims19
A power source for an aircraft comprising:
- a solid oxide fuel cell electrically coupled to a first power converter wherein the first power converter is electrically coupled to an aircraft distribution network to supply electricity to the aircraft;
- a proton exchange membrane fuel cell electrically coupled to a second power converter wherein the second power converter is electrically coupled to the aircraft distribution network to supply electricity to the aircraft;
- at least one battery electrically coupled to the solid oxide fuel cell, the proton exchange membrane fuel cell, and the aircraft distribution network to supply electricity to the aircraft and to be recharged by the solid oxide fuel cell and the proton exchange membrane fuel cell;
- and
- a solid oxide fuel cell multi-power unit electrically coupled to a third power converter wherein the solid oxide fuel cell multi-power unit is electrically coupled to the aircraft distribution network to supply electricity to the aircraft, to supply hydraulics to the aircraft, and to supply compressed air to the aircraft.
