A power generation system for an includes: a hydrogen fuel cell; an air supply system configured to supply air to the aircraft, the air supply system comprising an ORC-air heat exchanger; and an organic Rankine cycle (ORC) system comprising an organic fluid circuit. The organic fluid circuit is configured to receive excess fuel cell heat from the hydrogen fuel cell to heat organic fluid in the organic fluid circuit. The organic fluid circuit passes through the ORC-air heat exchanger such that the supply air heats the organic fluid in the organic fluid circuit. The ORC system is configured to extract power from the organic fluid.

Power generation system

A power generation system for an aircraft includes: a storage tank for storing hydrogen; a fuel cell configured to generate power from the hydrogen; a fuel supply line configured to supply the hydrogen from storage tank to the fuel cell; a fresh air supply line configured to supply air to a cabin air supply system; and a fuel-air heat exchange system, wherein the fuel supply line and the air supply line pass through the fuel-air heat exchange system such that the hydrogen cools the air in use.

Power generation system comprising a fuel cell

A ball valve assembly includes a ball element arranged to be rotated by rotation of a shaft in engagement with the ball element, the ball element having first and second flow channels defined therethrough, a first inlet port at a first end of said first flow channel, a first outlet port at a second end of the first channel, a second inlet port at a first end of the second flow channel and a second outlet port at a second end of the second channel.
