    Abstract: An onboard electrochemical system of an electrochemical cell including a cathode and an anode separated by an electrolyte separator is selectively operated in either of two modes. In a first mode of operation, water or air is directed to the anode, electric power is provided to the anode and cathode to provide a voltage difference between the anode and the cathode, and nitrogen-enriched air is directed from the cathode to an aircraft fuel tank or aircraft fire suppression system. In a second mode of operation, fuel is directed to the anode, electric power is directed from the anode and cathode to one or more aircraft electric power-consuming systems or components, and nitrogen-enriched air is directed from the cathode to a fuel tank or fire suppression system.

    Abstract: A fuel deoxygenation system for an aircraft includes a hydrocarbon recycler configured to recycle hydrocarbon gas into fuel. The hydrocarbon recycler includes a housing that partially defines an ullage channel configured to fluidly communicate with both an ullage of an aircraft fuel tank and a vent, wherein the housing partially defines a hydrocarbon recirculation channel configured to fluidly communicate with a liquid portion of a fuel tank. The hydrocarbon recycler also includes a membrane defining a sealing wall between the ullage channel and the hydrocarbon recirculation channel such that the membrane is in fluid communication with both the ullage channel and the hydrocarbon recirculation channel, wherein the membrane is configured to be permeable to hydrocarbons such that hydrocarbons in the ullage channel can pass through the membrane to the hydrocarbon recirculation channel and oxygen in the ullage channel to passes through to be vented.

    Abstract: A method for inerting a protected space. Process water is delivered to an anode of an electrochemical cell where a portion of the process water is electrolyzed to form protons and oxygen. The protons are transferred across the separator to the cathode, and process water is directed through a process water fluid flow path including a first side of a membrane. Gas is transferred to a second side of the membrane to form a de-gassed process water on the first side of the membrane, 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 inerting gas flow path to the protected space.

    Abstract: A system is disclosed for providing inerting gas to a protected space. The system includes an electrochemical cell comprising a cathode and an anode separated by a separator comprising a proton transfer medium. The cathode receives air from an air source and discharges an inerting gas to the protected space. The anode receives process water and discharges oxygen and unreacted process water to a process water fluid flow path. The process water fluid flow path includes a liquid-gas separator, and the liquid-gas separator includes an inlet and a liquid outlet each in operative fluid communication with the process water fluid flow path, and a gas outlet that discharges gas removed from the process water fluid flow path.

    Abstract: A system is disclosed for providing inerting gas to a protected space. The system includes an electrochemical cell including a cathode, an anode separated by a separator that includes an ion transfer medium, and an electrical connection to a power source or power sink. 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, and an anode fluid flow path is in operative fluid communication with a catalyst at the anode, and includes an anode fluid flow path outlet. A cathode supply fluid flow path is disposed between the protected space and the cathode fluid flow path inlet, and an inerting gas flow path is in operative fluid communication with the cathode flow path outlet and the protected space.
