Solid macromolecule electrolyte type fuel cell

Abstract

Abstract PURPOSE:To reduce ion conductive resistance and the contact resistance with an electrode to lessen voltage drop to current density by enabling thinning an ion exchange membrane in a solid macromolecule electrolyte type fuel cell. CONSTITUTION:A pair of ion exchange membranes, in which an ion exchange membrane of a solid macromolecule electrolyte type fuel cell is previously applied to and formed on each catalyst layer surface of a pair of electrodes, is made to be mutually integrated as a heat fusion body, and film-thinning and conductive resistance lowering are made possible. The ion exchange membrane is made a positive ion exchange membrane, which is made a membrane in which the solution of a fluororesin system positive ion exchange membrane is applied to an electrode catalyst layer surface to be heated and dried. Moreover the inner peripheral edge of a frame-like insulating sheet 6 is buried in the outer peripheral part of the positive ion exchange membrane in this structure.
