Abstract

Electrochemical sensor for measuring a gas concentration of a sampled gas with an electrochemical element, including an electrochemical pump cell with a first and a second electrode and with a gas chamber which is connected to the sampled gas via a gas inlet opening and in which one of the two electrodes is located, with the gas inlet opening being covered by a porous covering. Also a method for producing an electrochemical sensor of this type.
