DIAPHRAGMLESS CELL Russian patent published in 2009 - IPC C02F1/461 

FIELD: chemistry; electricity.

SUBSTANCE: diaphragmless cell is designed as metal cathode tube with perforated bottom. Cathode tube above its perforated section contains threaded-opened hole dielectric linear bushing closely fitting to internal surface of metal cathode tube with metal plain anode rod fixed in dielectric bushing with threaded screw portion partially goes outside the dielectric bushing. The working part of anode rod within perforated part of cathode tube is coated with platinum layer. Inert dielectric layers covers internal surface of cathode from its end face to the dielectric bushing, as well as and perforation hole surfaces. Inside of cathode tube over the dielectric bushing, there is galvanic cell battery with its positive terminal adjoining with its lower end the end threading of anode rod, and metal compression spring adjoining with its lower end the negative terminal of galvanic cell battery. Cathode tube is closed from above with a metal cover with upper end of compression spring resting on its bottom.

EFFECT: cell downsizing to pocket device supplied from independent voltage source.
