Galvanic cell, humidity sensors were investigated using a high temperature proton conductive solid electrolyte based on SrCeO3. A sensor of this type is one of the applications of a steam concentration cell, the concept of which was recently discussed. These sensors could be operated stably at elevated temperatures. Furthermore, they exhibit a linear e.m.f. response against logarithm of vapour pressure over a wide range, a good reproductibility, a very fast response time and small responses to impurity gases.
