Abstract
The performance of an ABx type metal hydride alloy is improved by adding an element to the alloy which element is operative to enhance the surface area morphology of the alloy. The alloy may include surface regions of differing morphologies.
Claims6
A hydrogen storage material having a bulk region and an interface oxide region, said interface region comprising metallic catalytic particles supported by a support matrix and voids, said metallic catalytic particles and said voids being distributed throughout at least one portion of the interface region, said volume fraction of voids in said interface region is greater than 5% and said voids being elongated channels having a cross-sectional dimension of greater than 20 Angstroms and a length greater than said cross-sectional dimension.
