A process for the fabrication of an electrochemical cell component which comprises an ion exchange membrane joined to a frame member formed from a dissimilar polymeric material, which process comprises the steps of: i) coating the border of at least one face of an ion exchange membrane with a solution in a solvent which is miscible with water of the polymeric material from which the same frame member is made, or of a polymeric material which is compatible with the polymeric frame material; ii) optionally allowing the said coated membrane to stand and/or drying the said coated membrane; iii) placing the coated face of the ion exchange membrane from step (i) or step (ii) in contact with said frame member; and iv) joining the coated ion-exchange membrane to the said frame member.
A process for the fabrication of an electrochemical cell component which comprises an ion exchange membrane joined to a frame member formed from a dissimilar polymeric material, which process comprises the steps of:
A process as claimed in any one of the preceding claims wherein the membrane is coated by roller coating, K-bar coating, painting or screen printing.
A process as claimed in any one of the preceding claims wherein the membrane is a cation exchange membrane.
A process as claimed in any one of the preceding claims wherein the coated membrane is dried in step (ii) using heat.
A process as claimed in any one of the preceding claims wherein the coated membrane is joined to the frame using heat and pressure.
A frame/membrane assembly which has been produced by a process as claimed in any one of the preceding claims.
