摘要： 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.

摘要： A filter for filtering nucleated cells that includes a body containing at least either a metal or a metal oxide as its main component; and plural through holes, each of which have a shape other than a square shape, formed therein. An arithmetic average roughness of a first side of the filter part is smaller than a size of a nucleus of the nucleated cells to be filtered.

摘要： Apparatuses and methods for producing hydrogen peroxide by performing coupled chemical and electrochemical reactions are disclosed. An electrochemical cell has a chemical reaction chamber configured to hydrogenate a shuttle molecule and an electrochemical chamber configured to electrochemically dissociate water to form hydrogen ions at an anode, and to reduce the hydrogen ions to atomic hydrogen at a cathode. The chemical reaction chamber and the anode chamber are separated by a metallic membrane. The metallic membrane acts as a cathode of the cell, a hydrogen-selective layer and a catalyst. The metallic membrane may comprise a layer of palladium or a palladium alloy. A layer of co-catalyst may optionally be electrodeposited on the layer of palladium or palladium alloy. An ion exchange membrane separates the metallic membrane and the anode chamber. The hydrogenated shuttle molecule may be supplied to a reactor for contacting an oxygen-containing gas to yield hydrogen peroxide.
