Systems and methods for refurbishing fuel cell stack components
摘要:
A method of refurbishing a singulated fuel cell stack interconnect includes scanning a first pulsed laser beam on an air side of the interconnect to vaporize seal and corrosion barrier layer residue without vaporizing a metal oxide layer located on the air side of the interconnect below the corrosion barrier layer residue, and scanning a second pulsed laser beam which is different from the first pulsed laser beam on the exposed metal oxide layer on the air side of the interconnect to reflow the metal oxide layer without removing the metal oxide layer.
