Method for bonding two plates together for a fuel cell, especially gluing bipolar plates in a fuel cell

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.

FLUORINE AND HYDROGEN-BASED ADHESIVE COMPOSITIONS AND METHODS OF MAKING THE SAME

Embodiments of the present disclosure pertain to adhesive compositions that include a fluorinated molecule and a hydrogen-containing molecule that are non-covalently associated with one another. The molecules may be non-covalently associated with one another through dipole-dipole interactions that create a fluorine-hydrogen electronegativity difference between at least some of the fluorine atoms of the fluorinated molecule and at least some of the hydrogen atoms of the hydrogen-containing molecule. The fluorinated molecule and the hydrogen-containing molecule may be in different phases, such as a liquid phase for one molecule and a solid phase for the other molecule. Additional embodiments pertain to methods of enhancing an adhesiveness of a surface by applying an adhesive composition of the present disclosure to the surface. Further embodiments pertain to methods of making the adhesive compositions by mixing a fluorinated molecule with a hydrogen-containing molecule such that the molecules become non-covalently associated with one another.
