Patent ID: 7629068

Claim:
Aircraft, comprising: a pressure cabin; a supply system having a first electrochemical reactor for generating energy, hydrogen, oxygen and clear water from grey water, a fuel containing hydrocarbon and air; wherein the first electrochemical reactor at least partly forms at least one of the aircraft's systems selected from the group consisting of an auxiliary power unit for generating pressurised air and electric energy, a ram air turbine, a clear water tank of a water system, a power unit generator for generating electric energy and an oxygen supply system; wherein the supply system comprises a gas-tight housing for security critical system components; wherein the supply system further comprises a pressure applying device for applying a pressure by means of an inert gas within the gas-tight housing, irrespective of the pressure outside the gas-tight housing; and wherein the first electrochemical reactor alone supplies a necessary amount of oxygen for an emergency case when a cabin pressure drops on account of a leakage of the pressure cabin.
