Abstract
The invention is directed to an electrochemical measuring cell for detecting gaseous components with an electrolyte which is disposed between a counter electrode and a measuring electrode provided with gas permeable pores. The pores are configured as channels partially or completely filled with the electrolyte and these channels have a diameter which does not exceed 10 micrometers with a channel length of up to 300 micrometers and a web thickness of not more than 5 micrometers. With this configuration, drift and memory effects are suppressed and the measuring sensitivity is increased and, on the other hand, the response time and the residual current are reduced. When the measuring cell is used as a dosimeter, the counter electrode and the measuring electrode are decoupled with respect to a mass transport in the electrolyte.
