Abstract: An integrated condensing heat exchanger and water separator includes a microporous graphite plate, one or more water passages defined at a first side of the microporous graphite plate, and one or more air passages defined at a second side of the microporous graphite plate opposite the first side. An air inlet operably is connected to the one or more air passages to direct a flow of air through the one or more air passages at a first pressure, and a water inlet is operably connected to the one or more water passages to direct a flow of water through the one or more water passages at a second pressure lower than the first pressure. The microporous graphite plate is configured such that moisture condenses from the flow of air onto the second side and is wicked through the microporous graphite plate to the one or more water passages.

Abstract: An exemplary fuel cell device includes a cell stack assembly having a plurality of fuel cells. A vapor barrier tape is wrapped around at least a portion of an exterior of the cell stack assembly. An exemplary method of managing moisture within a fuel cell stack assembly includes covering at least a portion of an exterior of the cell stack assembly with a vapor barrier tape to thereby maintain moisture within the cell stack assembly.

Abstract: An assembly has a plurality of fuel cell stacks with at least one wall. At least one manifold portion is provided outwardly of the at least one wall of each of the fuel cell stacks. The at least one manifold portion for a pair of the plurality of fuel cell stacks is on facing surfaces with an intermediate wall between the at least one of the manifold portions on the pair of the plurality of fuel cell stacks. A method of forming an assembly of a plurality of fuel cell stacks is also disclosed.
