US Patent 7927693 - Nanoporous hydrogen storage material

http://www.freepatentsonline.com/7927693.html

There have been several examples over the past two decades of various carbon nanomaterials such as fullerenes (e.g. C60) and nanotubes being useful as a hydrogen storage material for fuel cells. This latest patent is from Taiwan's Institute of Nuclear Energy Research Atomic Energy Council and teaches one variation which may further improve hydrogen storage capacity. Claim 1 reads:

1. A high capacity hydrogen storage material, comprising:

a microporous body, capable of absorbing hydrogen and comprising a plurality of micropores and at least a mesopore channel communicating with a plurality of nanopore channels, each nanopore channel being communicating with at least a micropore; and

a plurality of metal particles, formed at least on either surface of the mesopore or the nanopore channel, or of the micropores.
