A multi-axis fiber Bragg grating sensing system has a plurality of spatially distributed and mechanically isolated three dimensional multi-axis sensing towers, each having a plurality of connected nonparallel sensing pillars having a straight portion of a length and straightness to support a fiber Bragg grating and connected to at least one other of the three dimensional multi-axis sensing towers via a curved portion having a curvature radius equal to the minimum bend radius of an affixed optical fiber. The optical fiber has a plurality of fiber Bragg gratings and is affixed to each of the dimensional multi-axis sensing towers wherein a fiber Bragg grating is positioned along a straight portion of a sensing pillar of each of the towers. An interrogator captures and measures wavelength data from the fiber Bragg gratings for measuring multi-axis force information applied to each of the three dimensional multi-axis sensing towers.

Multi-axis fiber Bragg grating sensors and systems

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.
