摘要： A fuel cell system includes a water vapor transport device having a wet flow field layer having a coarse microtruss structure disposed between a pair of fine microtruss structures. The coarse and fine microtruss structures of the wet flow field layer are formed from a radiation-sensitive material. A dry flow field layer has a coarse microtruss structure disposed between a pair of fine microtruss structures. The coarse and fine microtruss structures of the dry flow field layer are also formed from a radiation-sensitive material. A membrane is disposed between the wet flow field layer and the dry flow field layer and adapted to permit a transfer of water vapor therethrough from the wet fluid to the dry fluid to form a humidified fluid.

摘要： Method and apparatus for cooling a fuel cell stack. The cooling system uses vaporization cooling of the fuel stack and supersonic vapor compression of the vaporized coolant to significantly increase the temperature and pressure of the liquid coolant flowing through a heat exchanger. By increasing the heat rejection temperature of the coolant delivered to the heat exchanger, the heat transfer area of the heat exchanger can be reduced and the mass flow rate of coolant can also be reduced. The increased fluid pressure is used to circulate the coolant through the cooling system, thereby eliminating the circulation pump associated with conventional systems.

摘要： A gasket for a fuel cell, wherein the gasket includes the use of two or more different materials as the gasket. For example, ethylene propylene diene monomer (EPDM) and/or the like, or another more chemically inert gasket material, is located inside or on an inboard position and is the wetted material that is exposed to the fuel cell operating environment. Silicone and/or the like, or another potentially contaminating material with better cold temperature sealability, is located outside or on an outboard position and does not come in contact with the fuel cell internal environment. One method of constructing such a gasket would be two include two parallel bead traces of the gasket materials on a polyimide (e.g., KAPTON®) carrier, or the like.
