Analytical review on the hydrogen multilayer intercalation in carbonaceous nanostructures: relevance for development of super-adsorbents for fuel-cell-powered vehicles.

The analytical consideration of some recent experimental and theoretical data on the hydrogen on-board storage problem shows the necessity and economical expediency of carrying out further basic studies and initiating a constructive discussion on the physical key-note aspects ("open questions") of the hydrogen sorption by carbon-based nanomaterials: Especially, on the hydrogen multilayer intercalation in carbonaceous nanostructures, their relevance for the development of super-adsorbents for fuel-cell-powered vehicles, i.e., storage materials, which satisfy most of the U.S. DOE targets. It is consistent with the U. S. National Academies' recent recommendations and manifestations of the critical situation of the hydrogen storage problem.
