Abstract

The invention relates to a multilayer electrode with a porous core structure produced by sintering and composed of an electrically conducting material for an electrolysis cell, especially with a solid electrolyte, in which the porous core structure contains at least two layers of spherical bodies made of metal packed densely together, said layers being formed by sintering and connected together, with the layer facing the electrolyte forming the active layer and being made as a fine layer of spherical bodies of the same or approximately the same size and the layer that covers the active layer on the back being made as a coarse layer of spherical bodies that are larger than the spherical bodies in the active layer.
