Abstract
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.
