Process of manufacturing an electrochemical gas sensor and electrochemical gas sensor

Abstract

A process of manufacturing an electrochemical gas sensor is provided and an electrochemical gas sensor is obtainable by this process. The process includes the steps of: providing a substrate, the substrate having a through opening configuration including one or more through openings formed in the normal direction of the substrate, applying electrode material to an upper surface of the substrate and/or to a lower surface of the substrate, bonding the electrode material and the substrate so that the through opening configuration is closed by the electrode material to obtain a contact surfaces configuration including one or more contacts electrically contactable on the lower surface of the substrate opposite to the upper surface.
