Abstract: An aircraft fuel tank ullage gas management system is disclosed. The system includes an electrochemical cell having a membrane electrode assembly that includes a cathode and anode separated by an electrolyte separator. A cathode fluid flow path is in fluid communication with the cathode, and receives the flow of cabin air from the cabin air fluid flow path and discharges nitrogen-enriched air. An anode fluid flow path is in fluid communication with the anode, and discharges oxygen or oxygen-enriched air. The electrochemical cell also includes water in fluid communication with the anode. The system includes an electrical power source and electrical connections to the anode and cathode for providing an electric potential difference between the anode and cathode. An ullage flow path receives nitrogen-enriched air from the cathode fluid flow path and delivers it to the fuel tank. An optional flow path delivers humidified oxygen-enriched air back to the cabin.

Abstract: A fuel tank inerting system is disclosed, comprising a fuel tank and an electrochemical cell comprising a cathode and an anode separated by a separator comprising an anion transfer medium. A cathode fluid flow path is in operative fluid communication with a catalyst at the cathode between a cathode fluid flow path inlet and a cathode fluid flow path outlet. An anode fluid flow path is in operative fluid communication with a catalyst at the anode, and includes an anode fluid flow path outlet. An electrical connected to a power source is arranged to provide a voltage difference between the anode and the cathode. An air source is in operative fluid communication with either or both of the cathode flow path inlet and the anode flow path inlet. An inert gas flow path is in operative fluid communication with the cathode flow path outlet and the fuel tank.

Abstract: An electrochemical separator includes an electrochemical reactor that has an anode and a cathode. An aqueous working liquid circulates through the electrochemical reactor. The aqueous working liquid contains water and electrochemically active organic molecules dissolved in the water. The electrochemically active organic molecules are quinones functionalized with one or more ionic groups.

Abstract: A system produces inert gas and generates electrical power with an electrochemical cell with an anode and a cathode separated by a proton transfer medium separator. The anode includes an oxygen evolution reaction catalyst and a hydrogen oxidation reaction catalyst, and the system is operated in alternate modes: a first mode in which water is electrolyzed at the anode with an oxygen evolution reaction catalyst to form protons and oxygen, the protons are transported across the separator to the cathode and reacted with oxygen at the cathode, and an inerting gas depleted of oxygen is discharged from the cathode; and a second mode in which protons and electrons are produced from a fuel at the anode with a hydrogen oxidation reaction catalyst, protons are transported across the separator to the cathode, and electrons are transported to the cathode through an electrical circuit to produce electrical power.

Abstract: Systems and methods for generating inerting gas on vehicles are described. The systems include a proton exchange membrane (PEM) inerting system and a pure water replenishment system configured to provide pure water to the PEM inerting system, wherein the pure water replenishment system is in fluid communication with the PEM inerting system to replenish water lost during operation of the PEM inerting system.

Abstract: A method of producing inert gas uses an electrochemical gas separator with a proton exchange membrane to produce oxygen-depleted air and a water vapor transport module to dehumidify oxygen-depleted air. A drying mechanism is leveraged in conjunction with the water vapor transport module to dry the oxygen-depleted air. The dried oxygen-depleted air is then used in a location requiring inerting.
