A Solid Electrolyte Oxygen Gauge for Monitoring Trace Quantities of Water Vapor in Hydrogen Gas

An oxygen gauge, capable of measuring water content in hydrogen gas as low as a few parts per billion, is described. The gauge consists of a solid state electrochemical concentration cell employing yttria doped thoria as an electrolyte. The performance of the gauge at four operating temperatures bet...

Description
Summary:An oxygen gauge, capable of measuring water content in hydrogen gas as low as a few parts per billion, is described. The gauge consists of a solid state electrochemical concentration cell employing yttria doped thoria as an electrolyte. The performance of the gauge at four operating temperatures between 600 and 900°C is evaluated.
