An electrolyzer or unitized regenerative fuel cell has a flow field with at least one channel, wherein the cross-sectional area of the channel varies along at least a portion of the channel length. In some embodiments the channel width decreases along at least a portion of the length of the channel according to a natural exponential function. The use of this type of improved flow field channel can improve performance and efficiency of operation of the electrolyzer device.

The present invention relates to a method for producing a polymer composite material, particularly an electrode (10) and/or a separator, for an electrochemical cell, particularly for a battery cell and/or fuel cell and/or electrolysis cell. In order to improve the production of polymer composite materials, in the form of electrodes and/or separators, for example, particularly for electrochemical cells, and the properties and/or functionality thereof, such as the specific energy density and/or electrical conductivity thereof, at least one swellable polymer (1) is mixed with a solvent quantity of at least one solvent (2), which can be absorbed completely in the at least one swellable polymer (1) by swelling the at least one swellable polymer (1) and which swells the at least one swellable polymer (1), and with at least one particulate material (3, 4). A polymer composite material, particularly an electrode (10) and/or a separator, for an electrochemical cell, particularly for a battery cell and/or fuel cell and/or electrolysis cell, is then formed from the mixture (1, 2, 3, 4).

This invention relates to apparatuses, systems and methods for the production and separation of gases in membraneless liquid alkaline electrolysis, and particularly to electrodes and electrode assemblies for use in a divergent electrolytic flow-through apparatus. The apparatus according to the invention comprises an inlet chamber; first and second permeable electrodes each having first and second sides and defining an inner aperture surrounding the inner region, the first sides of the first and second electrodes arranged to face each other to define an electrode gap within the inlet chamber; a first electrolytic solution inlet into the outer region and a second electrolytic solution inlet into the inner region; a first outlet in fluid flow communication with the second side of the first electrode, and a second outlet in fluid flow communication with the second side of the second electrode.

A novel cell for generating ozonated water, the cell comprises a nafion membrane separating a diamond coated anode, and a gold surfaced cathode enclosed within a cell housing with the catalyst side of the nafion membrane facing the cathode. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane, each housing portion having ridges to enhance substantially even flow of fluid over the cathode and anode. The housing portions contain O-rings in grooves to prevent leaks, and alignment features to keep the electrodes aligned. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports. The housing may also incorporate an integrated spectral photometer including a bubble trap.

An individual solid oxide cell (SOC) constructed of a sandwich configuration including in the following order: an oxygen electrode, a solid oxide electrolyte, a fuel electrode, a fuel manifold, and at least one layer of mesh. In one embodiment, the mesh supports a reforming catalyst resulting in a solid oxide fuel cell (SOFC) having a reformer embedded therein. The reformer-modified SOFC functions internally to steam reform or partially oxidize a gaseous hydrocarbon, e.g. methane, to a gaseous reformate of hydrogen and carbon monoxide, which is converted in the SOC to water, carbon dioxide, or a mixture thereof, and an electrical current. In another embodiment, an electrical insulator is disposed between the fuel manifold and the mesh resulting in a solid oxide electrolysis cell (SOEC), which functions to electrolyze water and/or carbon dioxide.
