Abstract:
1. A water generation system for the generation of water on board of an aircraft, the water generation system comprising: a fuel cell device having an exhaust for an exhaust gas; a condenser coupled to the exhaust of the fuel cell device such that the exhaust gas is cooled by cabin air, wherein the condenser comprises: an exhaust inlet fluidically coupling the exhaust gas from the fuel cell device with a condenser element; an outlet in fluid flow communication with the condenser element, the outlet comprising an outflow valve, such that the condenser element is capable of cooling the exhaust gas using cabin air, such that water is extracted from the exhaust air, and the outflow valve couples the condenser to an environment outside of the aircraft, such that a pressure drop occurs when the aircraft is at cruising altitude and the cabin air is drawn through the condenser and discharges into the environment outside of the aircraft after the cabin air has passed through the condenser element; and at least one separation volume, wherein the at least one separation volume changes a direction of flow of the exhaust gas within the condenser and separates water from the exhaust gas as the direction of flow of the exhaust gas is redirected back through the condenser element by the at least one separation volume.
