The invention provides an improved proton exchange membrane for use in electrochemical cells having internal passages parallel to the membrane surface comprising permanent tubes preferably placed at the ends of the fluid passages. The invention also provides an apparatus and process for making the membrane, membrane and electrode assemblies fabricated using the membrane, and the application of the membrane and electrode assemblies to a variety of devices, both electrochemical and otherwise. The passages in the membrane extend from one edge of the membrane to another and allow fluid flow through the membrane and give access directly to the membrane.

[ What is claimed is:] [15.] A membrane comprising:a sheet of ion exchange material that is electronically insulating having top and bottom surfaces, wherein the sheet forms a passage between the surfaces extending through the sheet in a plane that is substantially parallel to the sheet surfaces, wherein the passage has at least one compression resistant tube in direct fluid communication with the passage, and wherein the ion exchange material is a fluorinated ion exchange material selected from a group consisting of perfluorinated sulfonic acid polymers, perfluorinated carboxylic acid polymers, perfluoro bisulfonimide polymers, perfluoro phosphonic acid polymers, perfluorinated tetraalkylammonium salt polymers, carbanion acids, and mixtures thereof.
