An electrolytic cell of the filter press type comprising a plurality of anodes, cathodes and gaskets, and ion-exchange membranes positioned between each adjacent anode and cathode to form in the cell a plurality of anode compartments and cathode compartments, the cell having two inlet headers from which electrolyte may be charged to the anode compartments of the cell and from which liquors may be charged to the cathode compartments of the cell, and two outlet headers from which products of elect...

An electrolytic cell with spaced-apart electrodes in a row so constructed that the inter-electrode spaces are in series so that the electrolyte flows through them in succession. Preferably the electrodes are at least 1 centimeter thick and the inter-electrode spaces communicate with one another only by way of holes through the electrodes. The electrodes may be wedge-shaped.

An electrolytic cell having a heat exchanging shell disposed therein and dividing the cell container into an upper and lower electrolyte chamber. Electrode tube means extend through said shell and are in communication with said electrolyte chamber. Electrode means are disposed in said electrode tube means in a manner to preserve said communication. Downcomer tube means, interspersed among said electrode tube means, also extend through the shell into communication with said electrolyte chamber. A...

An improved electrolytic cell having collector elements arranged horizontally in the cell and extending to the sides thereof, and a slab of aluminum disposed horizontally at the bottom of the cell to which the collector elements are connected.

A process and cell produces an oxidant or reductant from a solution containing an electrolytically decomposable oxidation or reduction causing precursor compound for use with a waste solution, the oxidant or reductant being obtained by adding an electrolytically decomposable precursor compound to a solution in a vessel having an anode and cathode, one of which is isolated in a porous cup, so that when an electrical current flows between the electrodes the desired oxidizer or reductant will be fo...

The present invention relates to electrolytic capacitors containing an electrolyte which is substantially nonaqueous, in which said electrolyte contains a dissolved chemical compound capable, as a result of the high-operating temperatures of the capacitor, of decomposing while at the same time giving off water and leaving a residue which remains dissolved, both the proportion and the solvent of this compound being so chosen that the dehydration of the latter substantially compensates for the wat...

An electrolysis cell for purification of water containing dissolved chlorides by generation of chlorine or hypochlorite consists of coaxial tubular anode and cathode defining an annular flow passage for the continuous flow of the electrolyte and the inlet passages to the annular passage are arranged to produce a swirling motion of the electrolyte around the axis of the anode in order to prevent blocking of the narrow annular passage by deposits.

An improved anode for the electrolysis of brines is comprised of a corrosion resistant valve metal substrate, a thin porous adherent exterior coating of a refractory oxide which is inert to the electrolysis cell environment, and between the substrate and exterior coating a thin layer of ruthenium oxide.

An improved anode for the electrolysis of brine is comprised of a corrosion resistant valve metal substrate and a thin adherent exterior coating consisting esentially of ruthenium oxide and a carbide, the carbide being inert to the electrolysis environment. An especially effective anode has a coating of ruthenium oxide and boron carbide.

Gaseous products which tend to form at the anode or cathode of an electrolytic or electrochemical system in which the electrolyte is an aqueous medium may be converted into a reduction-oxidation reaction product through the action of a contacogen. In such electrolytic systems, hydrogen is usually produced at the cathode and oxygen or other gas may be produced at the anode. By placing a contacogen in gas receiving relation with the electrode at which a gas tends to be produced, and externally int...
