A 100 x 600 mm multilayered sheet with a single polycrystalline graphene layer (grain size 100-120 nm) formed on a bimetallic Cu/Pt substrate was placed in a vacuum plasma-chemical reactor with a pulsed laser. Al₄C₃ was ablated onto the graphene surface. After PMMA film attachment and selective Cu etching, a functionalized graphene sheet on a PMMA carrier was obtained. Carbon cores (140 mm long, 5 µm diameter) were attached by thermal welding. The PMMA carrier was dissolved in acetone and dried. The graphene was rolled into a cylindrical spiral roll, heated at 600°C under 10⁻⁶ Pa vacuum for 15 min. Final roll: diameter 30 µm, length 100 mm, weight 66 µg, density 0.76 g/cm³, spiral pitch 0.59 nm. Al₄C₃ particles covered ~2.04% of the inner surface. The roll was exposed to 99.996% pure hydrogen at 5 MPa and hydrogen content was measured by IR energy absorption after complete combustion, yielding 16 ppm hydrogen (~7.0 wt%).
