Hydrogen storage device

Abstract

A hydrogen storage device includes a hydrogen storage can, at least one first partition, and at least one second partition. The hydrogen storage can defines a major axis. The at least one first partition is used to partition the space in the hydrogen storage can into at least one compartment. The at least one second partition includes a plurality of sub-compartments. The sub-compartments are arranged linearly in at least one row perpendicular to the major axis.
