Abstract

In this work a micro-electrolysis cell is presented that allows the rapid generation of high pressure gas-liquid mixtures. The stainless steel electrolysis cell (150 µl volume) is constructed as an integral part of an automotive pressure sensor, allowing the on-line monitoring of the generated pressure. By the application of an electric current between two platinum electrodes inserted in the electrolyte filled cell, hydrogen and oxygen gas was generated with pressures up to 1350 bar. First experiments were performed to investigate the catalytic back-reaction of the generated hydrogen/oxygen mixture at the surface of the platinum electrodes. By the application of a compensation current to keep the internal pressure at a constant value, the rate of the back reaction could be established. It follows that the catalytic back-reaction rate increases exponentially above a pressure of 800 bar. As the proposed method of in-situ high pressure gas generation is intrinsically fast and safe due to the small cell volume, a large number of these cells/reactors can form a platform for (chemical) high throughput experimentation (HTE).
