An Actuation Principle: The Electrolysis of Water

In this paper the theory of water electrolysis in a closed electrochemical cell, that contains two electrodes, an electrolyte and a pressure sensor is described. From the leakage and electrochemical experiments done with this cell it is possible to obtain information about the applicability of the electrochemical principle in a closed cavity, the choice of the electrodes and electrolyte, and different types of leakages. Further, tests done with a control system, that consists of an electronic feedback system together with the electrochemical macro cell and the pressure sensor are presented. A value of the pressure is set and the regulator will actuate the electrochemical cell in such a way to get the desired pressure.
