HYDROGEN STORAGE MATERIAL, HYDROGEN SENSOR, AND HYDROGEN CONCENTRATION MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen storage material, a hydrogen sensor, and a hydrogen concentration measuring method, which acquire a higher detection sensitivity than an existing hydrogen sensor for detecting the concentration of hydrogen on the basis of changes in electric resistance and requiring no heating for preventing the occlusion of other than hydrogen since metal particles react with (occlude) only hydrogen.;SOLUTION: A hydrogen storage material is provided with both a nano scale template made of a negatively charged high polymer electrolyte and the metal particles to be deposited in the surface of the template for storing hydrogen and detects the concentration of hydrogen on the basis of changes in electric conductivity caused by both the inflation of the metal particles caused by the occlusion of hydrogen and the connection between the metal particles.;COPYRIGHT: (C)2010,JPO&INPIT
