HYDROGEN-ABSORBING ALLOY AND HYDROGEN SENSOR USING SAME

摘要

A hydrogen sensor using a hydrogen-absorbing alloy containing an Mg-Ni-based alloy and a Zr-Ti-based alloy includes a substrate (2), a hydrogen reaction layer (3) formed on the substrate (2) and containing the Mg-Ni-based alloy and the Zr-Ti-based alloy, and a first catalyst layer (4) formed on the hydrogen reaction layer (3) and capable of accelerating hydrogenation of the Mg-Ni-based alloy.
