Series of cells for use in an electrochemical device
A series of cells for use in an electrochemical device, such as an electrochemical cell or battery, that can operate in a single bulk electrolyte solution shared among the cells. Methods of producing hydrogen or both hydrogen and electricity in appreciable quantifies and in various ratios, and vehicles or other devices and applications powered by electrochemical devices comprising the series.
Anode assembly, contact strips, electrochemical cell, and methods to use and manufacture thereof
Provided herein are anode assembly, conductive contact strips, electrochemical cells containing the anode assembly and the conductive contact strips, and methods to use and manufacture the same, where the anode assembly includes a plurality of V-shaped, U-shaped, or Z-shaped elements positioned outside the anode shell and in electrical contact with the anode.
FLEXIBLE ELECTRICAL CONNECTORS FOR ELECTROLYTIC CELLS
A flexible electrical connector assembly is adapted to connect a bus bar of an electrolytic cell to a collector bar of the electrolytic cell. The assembly includes an electrical connector including a plurality of conductive metal sheets, the electrical connector having a collector bar end and a bus bar end. The electrical connector may be adapted for being joined, at the collector bar end, to the collector bar and, at the bus bar end, to the bus bar. The electrical connector may be adapted to implement a change in direction, at a bend along a current-carrying path between the bus bar end and the collector bar end, the bend assisting to define the change in direction as greater than 90 degrees.
HYDROLYZER
The invention is a hydrolyser capable of operating with simple water, instead of using demineralized water with chemical additions of salts and other compounds. It can use both spring water and any other type of water, such as drinking water, sea water or grey or waste water. Gets separate outputs of hydrogen and oxygen. It is proposed a mechanical and circuit solution which allows ionic migration between anodes and cathodes, such that it does not require the addition of potash or other salts or other chemical systems suitable for improving the conductivity of the water in the hydrolysis cell. The system allows a very wide parallel surface interface between anode and cathode, despite the physical distance between anode and cathode and their clear separation. The total resistance of the water for each hydrolytic cell is very low, i.e. a high conductivity through the water, conductivity obtained through the artifice of the so-called ionic bridge.
SOLID OXIDE CELL STACK COMPRISING INTEGRATED INTERCONNECT, SPACER AND MANIFOLD
A Solid Oxide Cell stack has an integrated interconnect, spacer and manifold, which is formed by bending a surplus part of the plate interconnect 180? to form a spacer part on top of the interconnect and connected to the interconnect at least by the bend and comprising overlapping primary and secondary gas inlet openings in adjacent layers in fluid connection.
Method for high-temperature electrolysis or co-electrolysis, method for producing electricity by means of an SOFC fuel cell, and associated interconnectors, reactors and operating methods
A heat exchanger can be integrated into an interconnector that can be used in both a SOFC fuel cell and an EHT electrolyser, which allows a heat-transfer fluid different from that in the reactive and drainage gas circuits to be circulated from the inlet of the reactor, thereby allowing the best possible management of the exothermic operating modes of the SOFC cell and the exothermic or endothermic operating modes of the EHT electrolyser and the SOFC cell, especially in the absence of current for the latter.
