Abstract
The present disclosure discloses a high temperature cell system. The cell system may comprise at least two distinct cathode chambers. The cell system may further comprise a separator having a hollow structure enclosed between a first wall and a second wall, wherein the separator is configured to enable ion transfer between the first wall and the second wall. Further the hollow structure of the separator may define at least one anode chamber. The cell system may comprise a base configured to provide a common sealing to the at least two cathode chambers and the separator at one first end and second end respectively.
Claims30
A high temperature cell system comprising:
- at least two distinct cathode chambers;
- a monolithic separator having a hollow structure enclosed between a first wall and a second wall, wherein the monolithic separator is configured to enable ion transfer between the first wall and the second wall;
- at least one anode chamber defined by the hollow structure of the monolithic separator;
- an outer metallic housing laterally surrounding the monolithic separator and the chambers, the housing being configured to act as an outer cathode within an outer of the cathode chambers;
- a central cathode located along a longitudinal centerline within a central of the cathode chambers, the central cathode being elongated along a majority longitudinal length of the central of the cathode chambers;
- a longitudinally elongated anode located within the anode chamber of the monolithic separator, and extending a majority longitudinal length therein;
- a lateral thickness of the anode being less than a lateral thickness of the central cathode;
- and
- a base providing a common sealing to the at least two cathode chambers and the monolithic separator at one end, wherein the monolithic separator is closed at an opposite end;
- a second separator including multiple walls with another anode therebetween, the separators being spaced apart from each other and having different lateral diameters and longitudinal lengths relative to each other;
- and
- multiple ceramic rings center and fix the central cathode, and the separators being joined to the ceramic rings.
A high temperature electrochemical cell system, comprising:
- a housing unit;
- at least one separator having a first wall and a second wall, located within the housing unit, the separator being a solid electrolyte;
- at least one cathode chamber formed by the housing unit and the at least one separator;
- a cathode electrode connected to the at least one cathode chamber;
- at least one anode chamber defined by a hollow portion formed between the first wall and the second wall of the at least one separator;
- and
- an anode electrode connected to the at least one anode chamber and disposed within the at least one separator between the first wall and the second wall;
- wherein the anode electrode laterally contacts against facing internal surfaces of the walls of the separator, and the anode electrode longitudinally extends a majority length of the hollow portion of the separator;
- wherein the at least one separator electrically insulates the at least one cathode chamber from the at least one anode chamber with one of the first wall or the second wall, and enables ion transfer between the first wall and the second wall;
- and
- a base located spanning between the first wall and the second wall, defining an enclosed bottom of the hollow portion within which is received the anode electrode, a gap being located between a bottom end of the anode electrode and the base, the hollow portion being entirely linearly aligned with the anode electrode therein, and the enclosed bottom of the hollow portion terminating laterally offset from the cathode electrode.
