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: A system is disclosed for providing inerting gas to a protected space, and also providing electrical power. The system includes an electrochemical cell comprising a cathode and an anode separated by a separator comprising a proton transfer medium. Inerting gas is produced at the cathode. A fuel source comprising methanol or formaldehyde or ethanol and a water source are each in controllable operative fluid communication with the anode. A controller is configured to alternatively operate the system in a first mode of operation where water is directed to the anode fluid flow path inlet and electric power is directed from a power source to the electrochemical cell, and in a second mode of operation in which the fuel is directed from the fuel source to the anode fluid flow path inlet and electric power is directed from the electrochemical cell to the power sink.

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.
