摘要： A composite plate-shaped fuel cell component includes two electrically conductive porous plates juxtaposed and in area electrical contact with one another at an interface, and a sealant body accommodated in and completely filling the pores of a sealed region of each of the porous plates that extends to a predetermined distance from the interface into the respective porous plate to form a fluid impermeable barrier between the porous plates and to bond the porous plates to one another at the interface. The sealant body includes at least one layer of a fluoroelastomer sealant that fills all of the pores of at least one of the sealed regions.

摘要： The coolant plate component of a fuel cell assembly is formed from a plate made from graphite particles that are bonded together by a fluorocarbon polymer binder and which encapsulate a serpentine coolant circulation tube. The coolant plate component is non-porous. The graphite particles are preferably flakes which pack together very tightly, and require only a minor amount of the polymer binder to form a solid plate. The plate will provide enhanced heat transfer, will conduct electrons, and will block electrolyte migration from cell to cell in a fuel cell stack due to its construction. The composition of the plate is graded so as to provide a varied coefficient of thermal expansion as measured through the thickness of the plate so as to reduce thermal stresses imposed on the fuel cell stack. The coolant circulation tube has a roughened outer surface which enhances adhesion of the encapsulating graphite flake/binder mixture without inhibiting heat transfer.

摘要： A fuel cell component that includes a porous fuel cell plate and a solid frame contiguously extending all around the fuel cell plate is made by first forming an integral plate-shaped porous body including a central portion constituting the fuel cell plate and a peripheral portion integral with and circumferentially completely surrounding the central portion, and then impregnating the pores of only the peripheral portion with a quantity of initially flowable but solidifiable impregnating material such that the impregnating material is accommodated in and completely fills such pores and makes the peripheral portion solid and completely fluid-impermeable upon solidification of the impregnating material to constitute the frame.

摘要： The reactant flow field on the cathode side of a fuel cell assembly is formed from a plate made from carbon particles that are bonded together by a fluorocarbon polymer binder. The cathode reactant flow field is non-porous, and is hydrophobic due to the presence of the poller binder. The carbon particles are preferably carbon flakes which pack together very tightly, and require only a minor amount of the polymer binder to form a solid plate. The plate will provide cathode reactant flow channels, will conduct electrons and heat and will minimize acid absorption in a fuel cell stack due to its hydrophobic nature.
