An enclosure for a fuel cell stack for insulating the hot zone of the fuel cell stack and for exchanging heat from the fuel cell stack to a reactant that passes through the enclosure to be used by the fuel cell stack. The enclosure comprises at least one chamber having an intake means for the reactant and an exhaust means for passing the reactant to the fuel cell stack. In one embodiment there are three layered chambers.

Fuel cell insulating heat exchanger

A heat exchanger has oil core plates and coolant core plates disposed in alternating, stacked relationship. Flow passages are provided between adjacent plates, so that the oil flow passages alternate with the coolant flow passages, and the oil can flow from an oil inlet opening of each oil plate, and through the oil flow passage to an oil outlet opening, and coolant can flow from a coolant inlet opening of each coolant plate through the coolant flow passage to a coolant outlet opening. The oil inlet openings are adjacent one end of the plates, and the oil outlet openings are spaced from the oil inlet openings, with a passageway for flow of the oil between upstanding bosses of the coolant plates on opposed sides of each oil plate and extending from a gap in an upstanding flange of the oil plate to the oil outlet opening.
