The adsorbent was simulated by a slit-like pore presented by the gap between two monocarbon (graphene) walls. In most cases, our results demonstrate a good agreement with the available experimental and theoretical results of other authors. A conclusion was made that, contrary to the low temperature region (T&lt;100 K), at high temperatures (200 and 300 K), predicted values for the adsorption and of the gravimetric density of hydrogen are not sufficient for the practical design of a hydrogen accumulator.</p></abstract><kwd-group xml:lang="en"><kwd>Adsorption</kwd><kwd>hydrogen</kwd><kwd>carbon adsorbents</kwd><kwd>density functional theory</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was supported by Russian Foundation for Basic Research (grant No 13-03 00119) and by Ministry of Education and Science of Russian Federation, in frames of the State Program in sphere of scientific activity.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Dillon A.C., Jones K.M., Bekkedahl T.A., Kiang C.H., Bethune D.S., Heben M.J.
