Outline of Final Research Achievements

It is demonstrated that ferromagnetic Pd alloy can be used to sense the hydrogen concentration in the gas phase using the changes in the magnetic susceptibility by the hydrogen uptake. A newly sensing system was constructed and a suitable sensing material for sensing hydrogen was investigated. As the results, the sensing system used PdCo coated Cu powder as detector makes it possible to detect 0.2vol% of hydrogen gas in air.
