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.

Fuel cell plate bonding method and arrangement

Ejectors () are configured to receive fresh fuel gas at the motive inlet () and to receive fuel recycle gas at the suction inlet (). Each ejector is disposed either a) within a fuel inlet/outlet manifold () or adjacent to and integral with the fuel inlet/outlet manifold. The ejector draws fuel recycle gas directly from the fuel outlet manifold and, after mixing with fresh fuel, is expanded () to lower the pressure and is then fed directly into the fuel inlet manifold (). The ejector may be within an external manifold () or an internal manifold (). The ejector () may be formed of perforations clear through a plate (), which is closed on either side by other plates (), or the ejector may be formed by suitable sculpture of fuel cells () having internal fuel inlet () and fuel outlet () manifolds.
