ABSTRACT:
A sensor is provided for precisely measuring the composition of mixtures of hydrogen and oxygen gas. The sensor has an active surface, at which hydrogen and oxygen are catalytically converted into water. A transport inhibiting barrier is disposed on the active surface. The heat released during the conversion is measured, and is indicative of the mixture composition.
