Abstract
Various embodiments provide systems and methods for detecting defects in components of a fuel cell. Embodiment methods and systems for detecting a defect in an interconnect for a fuel cell system include thermally exciting the interconnect using optical radiation and/or inductive stimulation, detecting a thermal response of the interconnect, and based on the thermal response, determining the presence or absence of a defect in the interconnect, such as a lateral or through crack in the interconnect.
