Nikolaev I. N., Kalinina L. N., Litvinov A. V. MIS sensors for hydrogen content measurements in 10Ė4Ö102 vol. % range

 

New types of MIS sensors which enable direct measurements of hydrogen concentration in a wider range (up to 10 vol. %) are developed. Their application combined with specialized sampling techniques allows to measure hydrogen concentrations up to 100 vol. %. Based on these MIS sensors, a new class of hydrogen analyzers can be developed for various applications in hydrogen power engineering.
