ELEKTRODE FÜR EINE ELEKTROCHEMISCHE ZELLE, DIE MIT EINER HOHEN DIFFERENZDRUCKDIFFERENZ ARBEITET, VERFAHREN ZUR HERSTELLUNG EINER SOLCHEN ELEKTRODE UND ELEKTROCHEMISCHE ZELLE ZUR VERWENDUNG EINER SOLCHEN ELEKTRODE

摘要

The invention relates to a porous electrode used in an electrochemical cell, containing a carrier and/or catalytic agent, which is characterized by that it consists of two or more layers with different average pore sizes, out of which layers the contact layer with the smallest average pore size is in contact with the membrane, and one or more supporting layers with a greater average pore size are linked to the other side of this contact layer. Furthermore, the invention relates to a procedure for the manufacturing of such electrodes and to electrochemical cells containing such electrodes.
