Abstract

Systems and methods for fuel cell stack part serialization and tracking. In an embodiment, a barcode may be applied to a fuel cell stack part which may identify the fuel cell stack part. In an embodiment, the barcode may be applied as ink on a green fuel cell stack part prior to sintering. In an embodiment, a portion of a fuel cell stack part may be imaged and pattern recognition techniques may be utilized to identify the fuel cell stack part based on the unique features of fuel cell stack part. In an embodiment, portion of a fuel cell stack part may be measured to generate one or more series of unique volume/area values and one or more series of unique volume/area values may be utilized to identify the fuel cell stack part.

Claims (19)

1. A method for tracking a fuel cell stack part, comprising:

forming a green fuel cell stack part;

applying a serialization to the green fuel cell stack part;

associating the serialization and the fuel cell stack part in a fuel cell part tracking database;

sintering the green fuel cell stack part to create a sintered fuel cell stack part, wherein the sintering permanently imprints the serialization onto the sintered fuel cell stack part;

identifying the serialization on the sintered fuel cell stack part; and

updating a status of the fuel cell stack part in the fuel cell part tracking database based on the identified serialization.

2. The method of claim 1 , wherein the serialization is a barcode.

3. The method of claim 2 , wherein the barcode is selected from the group comprising a single dimension barcode and a multi-dimensional barcode.

4. The method of claim 1 , wherein applying the serialization to the green fuel cell stack part comprises applying an ink to a surface of the green fuel cell stack part to print the serialization on the surface of the green fuel cell stack part.

5. The method of claim 4 , wherein applying an ink to a surface of the green fuel cell stack part to print the serialization on the surface of the green fuel cell stack part comprises inkjet printing the serialization on the surface of the green fuel cell stack part.

6. The method of claim 4 , wherein the fuel cell stack part is an interconnect or a fuel cell.

7. The method of claim 6 , wherein the fuel cell stack part is an interconnect and the ink comprises TiO 2 or the fuel cell stack part is a fuel cell and the ink comprises iron manganese oxide.

8. A method for tracking a fuel cell stack part, comprising:

forming a fuel cell stack part, wherein the part comprises a solid oxide fuel cell ceramic electrolyte or a chromium iron alloy interconnect for a solid oxide fuel cell stack;

applying a printed ink barcode serialization to the fuel cell stack part; and

associating the serialization and the fuel cell stack part in a fuel cell part tracking database.

9. The method of claim 8 , wherein the serialization is printed using the ink which is tolerant to at least 1250 degrees Celsius.

10. The method of claim 9 , wherein the barcode is selected from the group comprising a single dimension barcode and a multi-dimensional barcode.
