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.
