Abstract
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.

A power generation system for an aircraft, the power generation system comprising:
- 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;
- wherein 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,
- wherein 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,
- wherein the ORC system is configured to extract power from the organic fluid;
- the power generation system further comprising:
- a hydrogen supply system, the hydrogen supply system configured to supply hydrogen to the hydrogen fuel cell;
- wherein the hydrogen supply system comprises a hydrogen-air heat exchanger, wherein the air supply system is configured to pass air through the hydrogen-air heat exchanger to heat the hydrogen,
- wherein the hydrogen-air heat exchanger is downstream of the ORC-air heat exchanger in the air supply system.
