US Patent 7629068 Aircraft having integrated electrochemical supply system

An aircraft includes a supply system with an electrochemical reactor for generating energy, hydrogen, oxygen and clear water from grey water, a hydrocarbon containing fuel and air, so that the up to now separated systems for supply of clear water, generation of energy and generation of oxygen are combined to a combined system. The necessary redundancies may thereby secured by two or more systems of the same kind, which may be operated completely independently of each other.
