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： The present invention isolates the fluid streams flowing into and out of a fuel cell stack from the terminal plates so that the fluid streams and terminal plates do not come into contact with one another. The prevention of the fluid streams from contacting the terminal plate eliminates corrosion concerns associated with the terminal plate. The present invention accomplishes this isolation through the use of headers having fluid passageways therein that route the fluid streams in and/or out of the fuel cell stack while preventing contact between the fluid streams and the terminal plate.

摘要： A seal configuration is provided for a fuel cell stack, including a first bipolar plate and a second bipolar plate, each disposed on opposite sides of a membrane electrode assembly. The seal configuration includes a first sub-gasket adhered to a recess region of the first bipolar plate and a second sub-gasket adhered to a recess region of the second bipolar plate wherein the first and second sub-gaskets are disposed on opposite sides of the membrane electrode assembly. A seal member is disposed in the recessed regions of the first and second bipolar plates and between the first and second sub-gaskets. The seal configuration minimizes the size of the bypass regions around the seal perimeter and provide better control of the positions of all components during assembly of the fuel cell stack. The approach also reduces sensitivity to ambient relative humidity variations and reduces manufacturing costs by eliminating the need for humidity control in the production area.
