ABSTRACT:
A heat exchanger for a fuel cell stack includes a first plate and a second plate. The first and second plates are connected to one another by at least one wall. The first and second plates and the at least one wall form an enclosure having an interior area defined by interior surfaces of the enclosure. At least one liquid metal and transfer means are disposed within the interior area. The liquid metal flows within the transfer means and the interior area in response to a temperature gradient applied to the enclosure.
