Abstract

A multi-gas sensor includes a defined arrangement of working electrodes and a reference electrode. The reference electrode has two conductively connected single electrodes formed of respective different electrode materials. The working electrode and the single electrodes are preferably each disk-shaped and are arranged in two stacks one on top of another. A process is provided for a quantitative or qualitative determination of two target gases with the multi-gas sensor.
