摘要

PPROBLEM TO BE SOLVED: To provide a hydrogen occlusion technique capable of achieving a high density of hydrogen occluded per volume or mass and ensuring easy handling in storage and transportation. PSOLUTION: A hydrogen occlusion method is provided including: a step (S1) of subjecting a carbon material to gas activation; a step (S2) of subjecting the carbon material adjusted by the gas activation step to alkali activation; a step (S3) of housing a porous carbon produced by the alkali activation step in a vessel; and a step (S4) of introducing hydrogen into the vessel until an equilibrium pressure reaches 0.5-6 MPa, while keeping the interior of the vessel at a temperature within a range of 77-150 K. In the alkali activation step (S2), 3-8 times by weight as much potassium hydroxide as the carbon material is preferably added. PCOPYRIGHT: (C)2011,JPO&INPIT
