Abstract

A differential thermocouple hydrogen gas detector (10) is provided by coating one thermocouple junction (34) of a differential thermocouple pair (34, 36) with a Palladium-Silver alloy catalyst (46) and the other thermocouple junction (36) with a non-catalyst (52). Heated hydrogen gas reacts with the catalyst (46) to liberate heat to the catalyst coated thermocouple junction (34) in proportion to the concentration of hydrogen gas and proportionally raise the temperature of the catalyst coated junction (34) above that of the non-catalyst coated junction (36). The output signal (44) from the differential thermocouple device (34, 36) thus provides an output signal indicative of the concentration of hydrogen gas.
