Abstract

A planar palladium structure makes use of the unique properties of palladium to provide a hydrogen permeable membrane suitable for use in providing, for example, selective control of a nominal gas pressure within a cavity. The contemplated planar palladium structure includes a planar substrate having upper and lower major surfaces and an array of microfine channels therebetween, wherein the channels allow gaseous communication between the upper and lower major surfaces, and an array of palladium deposits being distributed on the substrate and located with respect to the microfine channels so as to restrict the gaseous communication to diffusion of hydrogen gas.
