Abstract

An electrochemical cell with a nonpartitioned electrolyte chamber and plane electrodes, which form a stack, the chamber filled by the electrolyte forming narrow gaps between the electrodes, and the electrode stack being assembled on a fixed baseplate so that its axis is essentially vertical.

Claims

1. In an electrochemical cell, wherein plane electrodes of circular shape are located in a conjoint electrolyte chamber and are spaced from 0.05 to 2 mm apart, the spacing being fixed by radial insulating strips, sets of several electrodes being so arranged, in the form of a stack, that with the exception of the outermost electrodes each electrode acts both as an anode and as a cathode, and the entire stack being accommodated in a closed reaction vessel and being provided with means whereby electrolyte liquid can be fed into the center of the stack, the improvement that the electrode stack is built up on a central baseplate which serves as a carrier, contains means of feeding-in the electrolyte liquid and is in electrically conductive connection with the plate stack whilst being electrically insulated from the reaction vessel.

2. A cell as claimed in claim 1, wherein the outermost electrodes of the stack can be brought into electrically conductive connection with a source of direct current and are provided with means for producing this connection.
