A radiation-assisted (typically solar-assisted) electrolyzer cell and panel for high-efficiency hydrogen production comprises a photoelectrode and electrode pair, with said photoelectrode comprising either a photoanode electrically coupled to a cathode shared with an anode, or a photocathode electrically coupled to an anode shared with a cathode; electrolyte; gas separators; all within a container divided into two chambers by said shared cathode or shared anode, and at least a portion of which is transparent to the electromagnetic radiation required by said photoanode (or photocathode) to apply photovoltage to a shared cathode (or anode) that increases the electrolysis current and hydrogen production.

Disclosed is a purification method of electrolytic gas generated from an electrolysis cell having a cathode and an anode. In a step of performing electrolysis of an electrolyte solution supplied into the electrolysis cell and repeating the electrolysis while circulating the electrolyzed electrolyte solution via an circulation tank disposed outside the electrolysis cell, a bag-shaped membrane pack, which is made from a specific porous membrane material, is of a shape having an opening at a top end thereof and closed at an entire side wall and entire bottom wall thereof and has a large permeation area at the entire side wall and entire bottom wall, is disposed in an interior of the circulation tank, thereby enabling to perform the electrolysis while purifying the electrolyte solution in which a portion of the electrolytic gas generated by the electrolysis is dissolved and bubbles of another portion of the electrolytic gas coexist.

The present invention is related to the field of microfluidics and compound distribution within microfluidic devices and their associated systems.

A fiber bundle cartridge for a fiber membrane degassing system includes an inner sleeve including one or more perforations and a fiber bundle positioned radially outward from the inner sleeve. The fiber bundle has an annular shape defining a central bundle axis. The perforations of the inner sleeve define a plurality of inlets and/or outlets facing radially with respect to the central bundle axis. A fiber membrane degassing system includes a housing defining a cylindrical volume having at least one inlet and at least one outlet. The system includes at least one fiber within the cylindrical volume, where fluid flowing through the cylindrical volume from the at least one inlet to the at least one outlet flows perpendicular to a longitudinal dimension of the fiber. A method of degassing a liquid includes directing a liquid volume through a fiber bundle in a direction radial to a longitudinally extending bundle axis.

A permeate device includes at least one non-porous, gas permeable element configured for contact with a liquid flow and at least one element fabricated from a porous material configured to permit gas flow therethrough. The permeate device may include a vacuum chamber that surrounds an operative portion of a permeation zone. A method for processing a liquid flow to remove entrained gas includes providing a liquid flow that includes an initial level of entrained gas, delivering the liquid flow to a permeate device, wherein the permeate device includes (i) at least one non-porous, gas permeable element configured for direct contact with the flow; and (ii) at least one element fabricated at least in part from a porous material configured so as to permit gas flow therethrough, and applying a negative pressure to the permeate device to draw entrained gas from the flow within an operative portion of the permeate device.

This disclosure relates to a separating element for separating gas bubbles from a liquid, in particular from hydraulic oil, which includes a volume body with an open-pored material structure which has a plurality of cells which are arranged offset with respect to one another in such a manner that a plurality of flow paths for guiding gas bubbles through the material structure run in labyrinth-like manner, wherein the material structure includes at least one contact region in which at least two of the flow paths approach one another at least in sections, so that, in operation, the gas bubbles guided on the flow paths contact one another and thus join together to form a larger gas bubble.
