Abstract: A method for bonding two plates together for a fuel cell, wherein the method comprises applying an adhesive to the surface of at least one of the plates and pressing the two plates together with the adhesive in between. The adhesive contains a mixture in the range of 0.01% to 30% PVDF and a solvent, and optionally a surfactant.

Abstract: A continuous automated process and production line for preparing an acid doped polybenzimidazole, PBI, polymer membrane film for use in a fuel cell, the process comprising a washing stage, a drying procedure, and a doping stage.

Abstract: A method for producing a separator plate, where thermoplastic polymer material and a powder of electro-conductive filler, ECF is kneaded at a kneading temperature above a glass transition temperature for the thermoplastic polymer material but below a melting temperature for the thermoplastic polymer material in order to provide a malleable but not molten compound and for causing fibrillization in the thermoplastic polymer material prior to hot-compacting the sheet in a press-form to form a separator plate. A production facility for practicing the method is also disclosed.
