Title: Circular electrochemical cell - which can be rotated about horizontal axis
Inventor: BECK FRITZ DIPL CHEM DR
IPC: H01M8/00
Filed: 1977-02-15
Abstract: Electrochemical cell consists of two parallel disc shaped electrodes mounted inside a frame of insulating material to form an enclosed electrolyte space. The cell is mounted on a horizontal axis and can be rotated about this by a drive wheel contacting it. The cell can be of circular or square cross-section. In the electrolyte space formed by the frame and the electrodes, a further pair of electrodes can be mounted. These are polarised by the two outer electrodes. The chambers in the electrolyte space are connected by channels. The cell has reduced energy and space requirement. Often this is achieved by recirculation through the cell but the problem with this is that the flow pattern is not uniform, gives erosion in some areas and dead spots in others. The cell described avoids this.
