POROUS COMPOSITE PRODUCT FOR THE PRODUCTION OF A CATALYTIC LAYER, IN PARTICULAR IN FUEL CELL ELECTRODES

A composite product is for an electrode of a fuel cell including a catalyst, an electrically conductive phase which supports such catalyst, a protonically conductive phase, and a porous phase. At least the contact between the catalyst and the electrically and protonically conductive phases, and prefer ably also the contact of the porous phase With the catalyst and With the electrically and protonically conductive phases, is improved or maximized. Each of the phases is individually continuous, and such phases are continuous with each other.
