Abstract
An assembly includes an SOEC/SOFC-type solid oxide stack, a clamping system for clamping the stack, including at least two clamping rods that can be used to assemble upper and lower clamping plates, and a coupling system for high-temperature fluid-tight coupling of the stack to a heating system for supplying and discharging gas. The coupling system includes a collector with collection ducts for supplying and discharging gas, each provided with a collecting port positioned facing a corresponding communication port of at least one of the upper and lower clamping plates, and seals each placed between a collecting port and a corresponding communication port.
Claims21
An assembly, comprising:
- an SOEC/SOFC-type solid oxide stack operating at a high temperature, including a plurality of electrochemical cells each formed by a cathode, an anode and an electrolyte interposed between the cathode and the anode, and a plurality of intermediate interconnectors each arranged between two adjacent electrochemical cells;
- a clamping system for the SOEC/SOFC-type solid oxide stack, including an upper clamping plate and a lower clamping plate, between which the SOEC/SOFC-type solid oxide stack is sandwiched, each clamping plate including at least two clamping holes, the clamping system further including:
- at least two clamping rods each for extending through a clamping hole of the upper clamping plate and through a corresponding clamping hole of the lower clamping plate for assembling the upper and lower clamping plates to each other, and
- clamping means at each clamping hole of the upper and lower clamping plates for cooperating with said at least two clamping rods for assembling the upper and lower clamping plates therebetween;
- and
- a high temperature sealed coupling system for coupling said SOEC/SOFC-type solid oxide stack to a heating system for gas feed and outlet, the coupling system being detachable and enabling said SOEC/SOFC-type solid oxide stack to be electrically insulated, wherein
- the coupling system includes:
- a collector comprising at least two collecting ducts for gas feed and outlet each provided with a collecting hole positioned facing a corresponding communication hole of at least one of the upper and lower clamping plates, and
- at least two seals each placed between a collecting hole and a corresponding communication hole;
- and
- the clamping means comprises:
- a first clamping nut, cooperating with a first end of one of the clamping rods inserted through a first clamping hole in the upper clamping plate, secured against an upper surface of the upper clamping plate;
- and
- a second clamping nut cooperating with a second end of the one clamping rod inserted through a second clamping hole in the lower clamping plate,
- wherein
- collecting holes of said at least two collecting ducts of the collector are positioned facing corresponding communication holes of the lower clamping plate;
- and
- the lower clamping plate is detachably disposed in contact with the seals and sealed to the collector only by the weight of the stack equipped with the clamping system.
