Abstract:
1. A gas-permeable plasma electrode adapted for use in a parallel plate reactor, the gas-permeable plasma electrode having: an electrically conductive container with a base which has a hole, through which gas is introduced into the gas-permeable plasma electrode; and a gas-permeable porous electrically conductive film, with the gas-permeable porous electrically conductive film being arranged opposite the base in the electrically conductive container and being connected to the electrically conductive container in such a manner that the gas-permeable porous electrically conductive film ends flush with the base of the electrically conductive container, and with the gas-permeable porous electrically conductive film having a layer sequence of two or more gas-permeable film elements each having at least one layer of electrically conductive grains, at least some of which are arranged so as to form a gas-permeable film, wherein the electrically conductive grains in each gas-permeable film element have a different diameter, and wherein the diameters of the electrically conductive grains in the individual gas-permeable film elements decrease from the base of the electrically conductive container.
