An electrolytic reaction system for generating gaseous hydrogen and oxygen includes a reaction chamber for accommodating an electrolyte as well as an electrode arrangement, which is formed of anodic and cathodic electrodes. Between lateral surfaces of electrodes arranged to be spaced apart from one another, at least one flow channel for the electrolyte is formed, which extends between a first axial end for admitting the electrolyte into the electrode arrangement and a second axial end for discharging the electrolyte out of the electrode arrangement. The at least one flow channel has at least one first flow cross-section and at least one second flow cross-section, wherein the second flow cross-section has a smaller size than the first flow channel, and the comparatively smaller second flow cross-section is formed in a partial section of the at least one flow channel closest to the second axial end of the electrode arrangement.

The present invention discloses a membrane-less reactor design for microbial electrosynthesis of alcohols from carbon dioxide (CO.sub.2). The membrane-less reactor design thus facilitates higher and efficient CO.sub.2 transformation to alcohols via single pot microbial electrosynthesis. The reactor design operates efficiently avoiding oxygen contact at working electrode without using membrane, in turn there is an increase in CO.sub.2 solubility and its bioavailability for subsequent CO.sub.2 conversion to alcohols at faster rate. The present invention further provides a process of operation of the reactor for biotransformation of the carbon dioxide.

A fluid electrolysis apparatus includes: a body part which includes an inlet port and an outlet port formed thereon and is provided with an inner space through which a fluid introduced through the inlet port passes to be discharged through the outlet port; an electrode part mounted in the inner space and including a first electrode plate and a second electrode plate, to which external powers of opposite polarity are applied, respectively, wherein the first electrode plate and the second electrode plate are alternately arranged while being spaced apart from each other, to form a plurality of fluid channels between the first electrode plate and the second electrode plate; and a conductive connection terminal part integrally formed with the body part so that at least a portion of a body thereof is embedded in the body part to apply external power to the electrode.

Electrochemical systems and methods for cleaving C—C bonds are disclosed. In performing the method, a reactant adsorption electrical potential, a C—C bond breaking electrical potential, and a desorption electrical potential are sequentially applied to an electrode pair contacting a composition initially containing a target chemical reactant, such as a polymer or alkane. As a result of performing the method, one or more desired chemical products, such as smaller alkane-containing molecules, are released from the electrode into the region between the electrode pairs. The method may be performed at ambient temperatures using renewable electricity.

A distributed hydrogen generating fence is formed from a plurality of electrolysis units and fence posts. Each unit includes one or more PV cells, an associated electrolysis system powered by electricity generated by the one or more PV cells, and a feed header for feeding water and an electrolyte to the electrolysis system. The electrolysis system is inside the feed header, and is operable to produce hydrogen and oxygen. The units are located between and are supported by mutually adjacent fence posts. The feed header extends in an inclined manner between the mutually adjacent fence posts. A gas header conducts at least the hydrogen from each of the plurality of units to a first remote facility. The fence includes openings allowing the passage of animals, people or vehicles. The openings can be controlled by a gate, or a grate laid across a hole in the ground spanning the opening.
