Abstract
An electrochemical gas sensor, which has a substantially more compact design and is manufactured with a considerably reduced manufacturing effort. A conical, calotte-shaped, hemispherical or cylindrical outer housing is provided with gas admission openings (3, 203). A cover (8, 208) as well as a layer structure is provided with, from the outside to the inside, the diffusion membrane (4, 204) with the electrodes (5, 6, 7; 205, 206, 207) applied thereto in a planiform manner, a layer (11, 211) consisting of a mat material or a porous body, which accommodates the electrolyte, and an electrolyte space (10, 210), which is filled at least partially with the electrolyte.
