ABSTRACT:
In order to improve a process for the production of a composite consisting of electrode material, catalyst material and a solid-electrolyte membrane for an electrochemical cell, in particular a fuel cell, with which solid-electrolyte material is brought into pore-deep contact with the electrode material and the catalyst material by softening it, such that this can be carried out as effectively and inexpensively as possible, it is suggested that a catalytic powder comprising electrode material, catalyst material and solid-electrolyte material be produced, that the catalytic powder be arranged on a surface area, that the catalytic powder be heated on a side facing away from the surface area in order to soften the solid-electrolyte material and that subsequently the catalytic powder be applied to the solid-electrolyte membrane under pressure with the side facing away from the surface area while the solid-electrolyte material is still softened in order to form a composite.
