Abstract (en)
[origin: WO0171332A1] A sensor element for the determination of gas component concentrations in exhaust gases from internal combustion engines is disclosed. The above comprises at least one gas measuring chamber (13) and at least one gas entry opening (17), by means of which the gas mixture may be introduced into the above gas measuring chamber (13) and at least one diffusion barrier (12), arranged between the gas entry opening (17) and the gas measuring chamber (13). The diffusion barrier (12) comprises at least one layer (14, 14a, 14b), made from catalytically active material, for adjusting the balance of the gas components.
