An electrode with adjustable gas permeability for electrochemical cells is
formed by first and second laminated thin layers. The first serves for
determining the overall gas permeability through the thickness of the
electrode and conducting electricity. The second is for conducting
electricity, supplying the reaction gases and removing the reaction
products, and is a porous electricity-conducting material. The laminate
consists of at least two materials of different gas permeability. The
material with the higher gas permeability located on the side of the
membrane forms the first layer, and the material with the lower gas
permeability forms the second layer on the side away from the membrane.
Openings are formed in the laminate towards the side adjacent to the
membrane. The sidewalls of the openings in the area of the material with
the higher gas permeability are at least partially covered by the
material with the lower gas permeability.
