Abstract
Cation exchange film is pressure bonded by hot-pressing on an aluminium foil for the solid high polymer electrolyte fuel cell which uses the cation exchange film as the electrolyte (PEMFC), but the conditions for the hot-pressing are severe because the softening temperature of polytetrafluoroethylene used as the binder for the bonding is higher than that of the cation exchange film. This invention is concerned with a method of improving adhesion and binding between the cation exchange film surface and the electrode catalyst layer, wherein K or Na type perfluorosulfonic acid system copolymer of the same material as that used for the cation exchange film is used as the binder in preparing the electrode catalyst layer of PEMFC, and the softening temperature of the cation exchange film itself is increased to enable high temperature hot-pressing. It is desirable to use the cation exchange film with the dry film thickness from 50 to 150[mu] and ion exchange capacity from 0.83 to 1.43 milli-equivalent/g (dry resin). 1 fig.
