Abstract
A support frame for electrolyte chambers in electrochemical cells with supported electrodes, having parallel wires extending in the direction of flow of the electrolytic liquid and arranged preferably between two thin screens, wherein the flow canals for the electrolytic liquid are substantially free of constrictions in the direction of flow.
Claims6
In an electrode assembly including powder electrodes and a support frame therefor, said support frame being for use in an electrolyte chamber in an electrochemical cell, said support frame including flow passages for an electrolyte liquid, the improvement comprising:
- the support frame comprising two thin porous boundary regions and a plurality of spaced parallel cross pieces disposed between said boundary regions, said cross pieces extending in the flow direction of the electrolytic liquid, for establishing flow passages in said support frame which are substantially free of constrictions in the flow direction, said support frame arranged between said powder electrodes, supporting and spacing said electrodes while at the same time conducting said electrolyte liquid.
In an electrode assembly including powder electrodes and a support frame therefor, said support frame being for use in an electrolyte chamber in an electrochemical cell, said support frame including flow passages for an electrolyte liquid, the improvement comprising:
- the support frame comprising two thin porous boundary regions having disposed therebetween a screen of corrugated shape so as to form flow canals extending in the direction of flow of the electrolytic liquid, for establishing flow passages in said support frame which are substantially free of constrictions in the flow direction, said support frame arranged between said powder electrodes, supporting and spacing said electrodes while at the same time conducting said electrolyte liquid.
A method of constructing powdered electrodes and an electrode assembly including a support frame therefor;
- said support frame being for use in an electrolyte chamber in an electrochemical cell, comprising:
- constructing the support frame of two thin porous boundary regions having disposed therebetween a screen of corrugated shape so as to form flow canals extending in the direction of flow of the electrolytic liquid, which are substantially free of constrictions in the flow direction;
- and supporting the supported powder electrodes in a spaced apart manner with said support frame.
