ELECTROCHEMICAL ENERGY CONVERTER Russian patent published in 2015 - IPC H01M8/12 H01M4/88 

FIELD: electricity.

SUBSTANCE: electrochemical energy converter includes electrodes, an electrical connector and a hard electrolyte layer made of a mixture of metal oxides including zirconium dioxide and an oxide of metal chosen from the group including calcium oxide, magnesium oxide, oxides of rare-earth elements or their mixtures, as well as electrode layers permeable for gases, which carry electrical current and coated on some part of their surface with contact layers. The converter is made in the form of a multi-row section, the rows of which are formed with tubular assemblies consisting of electrochemical cells made in the form of conical washers containing a hard electrolyte layer, as well as electrode layers, with central bushings forming an internal gas collector, in which current leads are arranged simultaneously. Some part of conical washers is separated between separators permeable for gas, and the other part of conical washers is separated with an external gas collector. Electrode layers located on the surface of the conical washers on their inner and outer sides have opposite polarities and are separated with a hard electrolyte layer; with that, the internal electrode layer and the external electrode layer are connected to current leads of the internal gas collector.

EFFECT: combination of tubular and planar structures in an electrochemical converter provides its stability for change of thermal loads.
