Claim:
1. An aircraft fuel deoxygenation and tank inerting system, comprising: an inert gas source configured to supply inert gas having an oxygen concentration of less than 3%; a fuel deoxygenation system adapted to receive fuel from a fuel source and the inert gas from the inert gas source, the fuel deoxygenation system configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel and oxygen-rich purge gas; and an air/fuel heat exchanger adapted to receive compressed air from a compressed air source and the deoxygenated fuel from the fuel deoxygenation system, the air/fuel heat exchanger configured to transfer heat from the compressed air to the deoxygenated fuel, to thereby supply cooled compressed air and heated deoxygenated fuel, wherein the inert gas source comprises:
