High capacity hydrogen getter assemblies

Abstract

A hydrogen getter assembly designed to address significant hydrogen outgassing and scavenging challenges may incorporate a triple-layered structure created through plating techniques. In this setup, the middle layer is made of a highly reactive metal foil from rolling mills that absorbs hydrogen by forming hydrides, while the plated foil surfaces are tailored for hydrogen adsorption. The combination of electroless plating and pulsed electroplating processes facilitates rapid hydrogen diffusion from the nano-scale grain layers to the micro-scale grain gettering layer. This design effectively reduces the interface kinetic energy barrier and enhances the absorption rate, especially at low temperatures, without needing thermal activation or regeneration. The materials and structural design allow these getters to function over a broad temperature range, from as low as −162° C. in cryogenic conditions to elevated temperatures of 200-300° C., achieving hydrogen absorption capacities more than 100 times greater than current getters.
