Patent number: 9678501Abstract: 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.Type: GrantFiled: January 7, 2014Date of Patent: June 13, 2017Assignee: BLOOM ENERGY CORPORATIONInventors: Stephen Couse, Tulin Akin, Matthias Gottmann, Harald Herchen, Arne Ballantine
