  • Patent number: 10800530
    Abstract: Disclosed are systems and methods of managing grey water or other recycled water onboard an aircraft based on demand within the aircraft. In some cases, the grey water is obtained from a lavatory or galley sink of the aircraft and is treated to purify and/or filter the grey water. The treated grey water can be routed within the aircraft according to a control scheme that accounts for demand within the aircraft. For example, some or all of the treated water may undergo electrolysis to produce oxygen gas (O2) and hydrogen gas (H2), some or all of which may be fed into the fuel cell system and used in a chemical reaction to produce electrical energy and other fuel cell by-products that can be directed to various aircraft systems and/or the aircraft cabin/lavatories.
