Abstract
An electrochemical gas sensor (1) having a stacked assembly of at least one first electrode (3) and a second electrode (6), which are respectively arranged on a carrier membrane (2, 5), and a separator (4) arranged between the electrodes (3, 6), including a gas conduction path (14) between the first electrode (3) and the second electrode (6). The gas conduction path (14) is constituted within the structural space defined by the electrodes (3, 6).
Claims9
An electrochemical gas sensor (1), comprising:
- a stacked assembly of at least one first electrode (3) and a second electrode (6), which are arranged on respective carrier membranes (2, 5);
- a separator (4) arranged between the at least one first electrode and the second electrode (3, 6);
- and
- a gas conduction path (14) constituted between the at least one first electrode (3) and the second electrode (6);
- the gas conduction path (14) is constituted within a structural space defined by the at least one first electrode and the second electrode (3, 6);
- wherein at least one feedthrough opening (11) is arranged in the separator (4), by which the gas conduction path (14) is constituted;
- at least one feedthrough opening (11) is arranged in the carrier membrane (2) of the at least one first electrode (3) that is aligned with the at least one feedthrough opening (11) in the separator (4);
- and
- wherein gas diffusion between the at last one first electrode and the second electrode only occurs through the gas conduction path.
