An apparatus is provided for the storage and dispensing of a sorbable gas. The apparatus includes a storage and dispensing vessel constructed and arranged for containing a solid-phase physical sorbent medium having a sorbable gas adsorbed by said sorbent medium. The dispensing vessel includes a top head having a dispensing valve coupled to the vessel for discharging the sorbable gas therefrom. The dispensing valve is in fluid flow communication with a wick that extends below the upper third of the vessel top head. The wick collects the sorbable gas for discharge of the gas through the dispensing valve.

The invention generally relates to a process for purifying a hydrogen gas for use in a fuel cell. The process involves taking a hydrogen feed stream from a high-pressure tank and passing it through a purifier comprising an adsorbent to provide a purified hydrogen stream which is sent to a fuel cell. A particular adsorbent which can be used is a metal-organic framework composition. The adsorbent can be housed in a device such as a canister or cartridge having an inlet and outlet port.

A method of adsorbing a highly reactive gas onto an adsorbent material comprising adsorbing the highly reactive gas to the adsorbent material. The adsorbent material comprises at least one Lewis basic functional group, or pores of a size to hold a single molecule of the highly reactive gas, or inert moieties which are provided to the adsorbent material at the same time at the same time as the highly reactive gas, prior to adsorbing the highly reactive gas or after adsorbing the highly reactive gas, or the highly reactive gas reacts with moieties of the adsorbent material resulting in passivation of the adsorbent material. A rate of decomposition of the adsorbed highly reactive gas is lower than a rate of decomposition for the neat gas at equal volumetric loadings and equal temperatures for both the adsorbed highly reactive gas and the neat gas.
