1. 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 until the adhesive bonds the plates together, wherein the adhesive contains a mixture of PVDF and a solvent, wherein the method comprises providing the adhesive by mixing PVDF and solvent and heating and stirring the mixture for dissolution of the PVDF in the solvent at a PVDF concentration in the adhesive; wherein the method comprises mixing PVDF in the solvent to a concentration in the range of 0.01% to 30% by weight PVDF relatively to the weight of the solvent for providing the adhesive.
