Abstract
A solid state cell for measuring the activity of a component of a mixture using a solid ionic conductor, which is in contact on one side with a reference phase and on the other side with a phase sensitive to the gas component to be determined, is to be improved in such a manner that its detection sensitivity and measuring stability are increased. For this purpose, the gas sensitive phase contains an addition of a substance that increases the electronic conductivity and does not chemically react with the components of the sensitive phase and the gas to be determined.
