Abstract: Hydrogen-producing fuel processing systems and related methods. The systems include a hydrogen-producing region configured to produce a mixed gas stream from a feedstock stream, a hydrogen-separation membrane module having at least one hydrogen-selective membrane and configured to separate the mixed gas stream into a product hydrogen stream and a byproduct stream, and an oxidant delivery system configured to deliver an oxidant-containing stream to the hydrogen-separation membrane module in situ to increase hydrogen permeance of the hydrogen-selective membrane. The methods include operating a hydrogen-producing fuel processing system in a hydrogen-producing regime, and subsequently operating the hydrogen-producing fuel processing system in a restoration regime, in which an oxidant-containing stream is delivered to the hydrogen-separation membrane module in situ to expose the at least one hydrogen-selective membrane to the oxidant-containing stream to increase the hydrogen permeance of the at least one hydrogen-selective membrane.

Abstract: A hydride flow reactor includes a tank configured to receive a hydride fuel. The reactor also includes a tubular member coupled to the tank and configured to receive the hydride fuel from the tank. The reactor also includes a transporter positioned at least partially within the tubular member and configured to transport the hydride fuel through the tubular member. The reactor also includes a heater positioned at least partially around the tubular member and the transporter. The heater is configured to heat the hydride fuel in the tubular member to convert the hydride fuel into hydrogen gas and a reacted byproduct.

Abstract: A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.

Abstract: A fuel tank inerting system includes a primary catalytic reactor comprising an inlet, an outlet, a reactive flow path between the inlet and the outlet, and a catalyst on the reactive flow path. The catalytic reactor is arranged to receive fuel from the fuel tank and air from an air source that are mixed to form a combined flow, and to react the combined flow along the reactive flow path to generate an inert gas. The system also includes an input sensor that measures a property of the combined flow before it enters the primary catalytic reactor and an output sensor that measures the property of the combined flow after it exits the primary catalytic reactor.

Abstract: An ejector has an interior nozzle, an exterior nozzle, a suction part, a mixing part and a diffuser part. The interior nozzle and the exterior nozzle are arranged coaxially with each other. A driving fluid is supplied to the interior nozzle and/or the exterior nozzle. The suction part is arranged on an outer periphery of the exterior nozzle and sucks a suction fluid by a driving fluid jet ejected from the interior nozzle and/or the exterior nozzle. A mixing part mixes the driving fluid jet with the suction fluid, and supplies a mixture fluid. The diffuser part reduces a flow speed of the mixture fluid and ejects the mixture fluid outside. An outlet part of the interior nozzle is arranged at an upstream side of the ejector more than an outlet part of the exterior nozzle along the axial direction of the ejector.
