Abstract

Ein Diaphragma für alkalische Elektrolysen, insbesond­ re für die alkalische Wasserelektrolyse, mit einer feinporö­ sen, insbesondere keramischen Schicht, die vorzugsweise von einem gerüstgehenden Träger oder Netz gestützt wird und an der die Elektroden sandwichartig anliegen, wird mit über die Fläche verteilten, in die feinporöse Schicht integrier­ ten gröberen Körnern ein- oder beidseitig versehen, die aus der Oberfläche vorragen und trotz anliegender Elektrode für einen gewissen Minimalabstand zwischen Diaphragma und Elektrode sorgen, so daß durch unvermeidbare Korrosions­ phänomene innerhalb der Apparatur bedingte Abscheidun­ gen auf den Elektroden nicht in das Diaphragma hineinwach­ sen können. Diese gröberen Körner von etwa 10 - 250µm werden bei der Herstellung des Diaphragmas vor dem Sintern in dünner verteilung auf die Oberfläche gebracht und unter geringer Druckanwendung in die Oberfläche soweit hineingetrieben, daß sie noppenartig daraus vorstehen. A diaphragm for alkaline electrolysis, in particular re for alkaline water electrolysis, with a fine por sen, especially ceramic layer, which preferably is supported by a gantry or network and where the electrodes are sandwiched with distributed over the surface, integrated into the fine porous layer The coarser grains are provided on one or both sides protrude from the surface and despite the electrode attached for a certain minimum distance between the diaphragm and Ensure the electrode so that corrosion cannot be avoided phenomena within the apparatus Do not wax on the electrodes into the diaphragm can sen. These coarser grains of about 10 - 250 µm are used in the manufacture of the diaphragm before Sintering brought to the surface in a thin distribution and so far under little pressure in the surface driven in so that they protrude from it like pimples.
