Abstract (en)
[origin: WO2010091761A1] The invention relates to a sensor element of a gas sensor for determining gas components in gas mixtures, comprising a field effect transistor and/or a diode, comprising a changing current flow upon contact with a gas to be detected, and positioned to be protected by a protective cap against direct inlet of the gas mixture. According to the invention, the protective cap (18) comprises a heating means (24), a glass former (34), and/or an oxidation catalyst (32).
