ELECTROCHEMICAL REDUCTION OF METAL OXIDES

摘要

A cathode element for use in an electrochemical cell for carrying out an electrochemical process for reducing a metal oxide such as a titanium oxide in a solid state is disclosed. The cathode element includes a honeycomb-shaped structure that includes a series of interconnected walls (103) that define a plurality of passages (97) for an electrolyte in the cell to penetrate the structure to contact internal exposed surfaces of the structure.
