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: Redundant electrochemical systems and methods for vehicles are described. The systems include a first electrochemical device located at a first position on the vehicle wherein the first electrochemical device is configured to generate at least one of inert gas, oxygen, and electrical power and a second electrochemical device located at a second position on the vehicle wherein the second electrochemical device is configured to generate at least one of inert gas, oxygen, and electrical power. The first electrochemical device is configured to operate in a first mode during normal operation of the vehicle and a second mode when the second electrochemical device fails, wherein in the second mode, the first electrochemical device provides the at least one of inert gas, oxygen, and electrical power for at least one vehicle critical system of the vehicle.

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: An inert gas generating system includes a source of a liquid hydrocarbon fuel, and a fractioning unit configured to receive a portion of the liquid hydrocarbon fuel from the source. The fractioning unit includes a perm-selective membrane configured to separate the portion of the liquid hydrocarbon fuel into substantially sulfur-free vapors and a sulfur-containing remainder. The system further includes a catalytic oxidation unit configured to receive and react the substantially sulfur-free vapors to produce an inert gas.

Abstract: A gas inerting system employs a carbon dioxide separation unit to remove carbon dioxide and water from an oxygen depleted gas stream generated from a catalytic oxidation unit and subsequently provides a nitrogen rich inerting gas to a fuel tank and/or to a cargo hold. A method of producing an inert gas passes an oxygen depleted gas stream from a catalytic oxidation unit through a carbon dioxide separation unit and provides a nitrogen rich inerting gas for fuel tank inerting and/or cargo hold fire suppression.

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.
