摘要

A hydrogen storage material including: molecular layers L 1 to L i+2 which are stacked on one another in parallel and mainly composed of six-membered rings having carbon atoms; and protrusions Pr 1a to Pr i protruding from atomic planes of adjacent molecular layers L 1 to L i+2 by lengths of not more than interlayer distances d 1 to d i+2 of the adjacent molecular layers.
