Provided in order to avoid or at least reduce the problems produced by the passive electrode of a heart pacemaker system is a layer having a high double layer capacitance at the phase boundary with the bodily fluid. Advantageous to that end is a porous layer comprised of a carbide, nitride or carbonitride of at least one of the metals titanium, vanadium, zirconium, niobium, molybdenum, hafnium, tantalum or tungsten. The layer can also be comprised of activated carbon with a microporous exposed surface. The layer is produced in the simplest manner by means of roughening the existing electrode surface at its active area.
