Abstract: A fuel cell assembly, a heat pipe for such a fuel cell assembly, and a fuel cell stack. The fuel cell assembly includes a fuel cell having an MEA structure, and a pair of heat pipe separator plates in physical and thermal contact with a planar surface of the fuel cell. Each heat pipe separator plate includes an external heat transfer fin to dissipate a portion of the heat generated by the fuel cell through exposed outer peripheral edges thereof. Each heat pipe separator plate also includes voids formed in an interior planar surface thereof, to be aligned with voids of other heat pipe separator plates when the fuel cell assembly is arranged in a stack. Upper voids are to define upper interior channels in fluid communication with a portion of the air stream supplied to the cathode. A heat transfer insert is arranged in the upper voids, and includes internal heat transfer fins to dissipate another portion of the heat into the upper interior channels for contact with the air stream.

Abstract: One or more methods of fabricating a microscale canopy wick structure having an array of individual wicks having one or more canopy members. Each method includes selectively etching a substrate to control the thickness of the canopy members and also control the width of a fluid flow channel between adjacent wicks in a manner that enhances the overall performance of the microscale canopy wick structure.
