An illustrative example fuel cell manifold assembly includes a metal manifold pan. A polymer material liner that is self-supporting includes a primary wall situated adjacent an interior of the manifold pan. The liner has a channel around a periphery of the liner and a portion of the manifold is received in the channel. A reactant conduit adapter is received through respective openings in the manifold pan and the liner. The reactant conduit adaptor includes a flange that is received against an interior surface on the primary wall of the liner with an interface between the flange and the interior surface being sealed. Another portion of the reactant conduit adaptor is adjacent an exterior of the manifold pan that faces in an opposite direction from the interior surface on the primary wall.

A method of manufacturing a porous structure for a fuel cell is disclosed. The method includes providing the porous structure, and processing the porous structure to selectively produce a non-porous region on the porous structure. In one example, the non-porous region is provided at the perimeter of the porous structure, an edge of an internal manifold and/or a surface or recess that supports a seal or gasket. The non-porous region has a porosity that is less than the porosity of the porous structure. The non-porous region prevents undesired leakage of fluid from the porous structure and prevents migration of adhesive associated with the seals.

An illustrative example embodiment of a fuel cell manifold device includes a self-supporting polymer material liner body including a generally planar primary wall and a plurality of side walls. The side walls respectively extend generally perpendicularly from the primary wall. Interior surfaces on the primary wall and the side walls collectively define a cavity. The primary wall has a length and a width that is smaller than the length. The primary wall includes a plurality of ribs situated width wise along the primary wall. The ribs are spaced apart from each other in a lengthwise direction. The ribs allow for some thermal expansion of the liner body.

An exemplary method of applying a seal to a fuel cell component includes providing a release layer on one side of a seal. The release layer has reinforcing fibers. Another side of the seal is placed against a selected portion of the fuel cell component. The seal, release layer and fuel cell component are heated. The release layer is then removed after the seal is secured to the fuel cell component.

An example method of securing a bond film to a fuel cell component includes positioning the bond film adjacent the fuel cell component and melting the bond film using thermal energy from an injection molded seal.
