Abstract
Official abstract text for this publication.
System and methods for refurbishing fuel cell stack components, the methods including singulating the stack using a splitting apparatus or a liquid nitrogen bath. Fuel cell debris may be removed from interconnects of the fuel cell stack using laser heating, flame heating, a die, sonication, a nubbed roller, grit blasting, and/or a high pressure fluid.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of removing fuel cell debris from an interconnect, the method comprising scanning a laser beam across the fuel cell debris adhered to the interconnect to remove the debris. 2 . The method of claim 1 , wherein the fuel cell debris comprises at least one of a ceramic electrolyte or a seal material. 3 . The method of claim 2 , wherein scanning the laser comprises irradiating opposing sides of the interconnect with one or more laser beams. 4 . The method of claim 3 , wherein the opposing sides of the interconnect are irradiated simultaneously. 5 . The method of claim 2 , wherein scanning the laser beam comprises scanning the laser beam while the interconnect is disposed in a vertical position.
