Abstract: A system for providing inerting gas to a protected space is disclosed. The system includes an electrochemical cell that produces inerting gas on a cathode fluid flow path, and delivers it to an inerting gas flow path is disposed in operative fluid communication with the cathode fluid flow path outlet and the protected space. The inerting gas flow path includes a condenser that receives inerting gas from the cathode fluid flow path outlet, and also includes a pressure control device configured along with the pressurized gas source to provide a pressure at the condenser greater than ambient pressure.

Abstract: A fuel tank inerting system includes an air separation module with an oxygen permeable membrane and a variable vacuum source in fluid communication with the air separation module. The variable vacuum source provides an adjustable vacuum to the permeate side of the oxygen permeable membrane in the air separation module, driving production of inert gas for fuel tank inerting or fire suppression.

Abstract: An air inert gas generating system consists of heat exchangers, a heating element, and a plurality of solid oxide electrochemical gas separator (SOEGS) cells. The SOEGS cells are interconnected in series to create a stack. A voltage is applied to the stack causing oxygen ions to be transported from the air flowing through the cathode through the electrolyte to the anode side of the SOEGS, resulting in oxygen-depleted gas. The oxygen-depleted gas can be used to inert the ullage of aircraft fuel tank or support the fire suppression system in the cargo hold. The oxygen-enriched gas can be used for other purposes.

Abstract: An onboard inert gas system has an electrochemical and a membrane gas separator. The electrochemical separator includes an electrochemical cell including a cathode and anode separated by an electrolyte separator. An electrical power source provides power to the electrical circuit at a voltage that electrolyzes water at the anode and forms water at the cathode, or reduces oxygen at the cathode and forms oxygen at the anode. Oxygen is consumed at the cathode, providing nitrogen-enriched air. Nitrogen-enriched air from the cathode is connected by a flow path to the membrane gas separator, which comprises a membrane having a greater permeability to oxygen or water than to nitrogen. Nitrogen-enriched air from the membrane gas separator that is further enriched in nitrogen, reduced in water content, or both, is connected by a flow path to a fuel tank, a fire suppression system, or both a fuel tank and a fire suppression system.

Abstract: An on-board aircraft inert gas system includes a source of hydrocarbon, a source of gas comprising oxygen, and a first fluid flow path between the source of gas comprising oxygen and an inert gas output. A reactor is disposed along the first fluid flow path that reacts oxygen and hydrocarbon from the fuel tank gas space to produce an oxygen-depleted gas. A heat exchanger condenser removes some water from the oxygen-depleted gas. A water-permeable gas membrane separator receives the oxygen-depleted gas from the heat exchanger and outputs dried oxygen-depleted gas.

Abstract: A system and method of inerting a protected space is disclosed. In the system and method, process water is delivered to an anode of an electrochemical cell comprising the anode and a cathode separated by a separator comprising a proton transfer medium. A portion of the process water is electrolyzed at the anode to form protons and oxygen, and the protons are transferred across the proton transfer medium. Process water is directed to a baffle to form de-gassed process water and the de-gassed process water is recycled to the anode. Air is delivered to the cathode and oxygen is reduced at the cathode to generate oxygen-depleted air. The oxygen-depleted air is directed from the cathode of the electrochemical cell along an inert gas flow path to the protected space.
