ABSTRACT:
In order to improve the mechanical properties in the area of the passive electrode given bipolar electrodes, the active region of the passive electrode exhibits a surface layer that has a high double layer capacitance at the phase boundary with the body fluids. The size of the passive electrode can be considerably reduced as a result. Particularly suitable as the surface layer is a porous layer consisting of a carbide, nitride or carbonitride of at least one of the metals titanium, vanadium, zirconium, niobium, molybdenum, hafnium, tantalum or tungsten. A layer of activated carbon with a surface having a porous microstructure or, in the simplest case, a roughened surface are also suitable.
