1. A carbon based electrode with a large total geometrical surface area of greater than 400 cm2, the electrode comprising a frame of an electrically conductive material with multiple cut-outs with a surface area, which cut-outs are separated from each other by portions of the electrically conductive material, wherein carbon based sub-electrodes dimensioned so as to at least cover the surface area of the cut-outs are positioned in the cut-outs and are conductively connected to at least part of each of the portions of the electrically conductive material adjacent to the carbon based sub-electrodes, wherein each of the sub-electrodes contains a current density distributor, wherein the frame has an electric conductivity which differs from the electric conductivity of the current density distributor by a maximum of 10% and/or wherein the frame has an electrical resistance which is the same as or smaller than the electrical resistance of the current density distributor.
