Abstract
Abstract A hydride storage for hydrogen comprises a preferably tubular solid casing for the storage material. In the interior of the casing, the storage material is bounded by a wall of a fabric, particularly metallic fabric, through which the hydrogen penetrates into, and out of, the material. Preferably, a highly elastic conduit (tubular body) permeable to gas and made of a metallic fabric is embedded in the storage material.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
118 words
A hydride storage for hydrogen comprising a rigid tubular housing containing a storage material therein having one closed end and an opposite end with an external connection, means defining a bore in said external connection and into said housing for the flow of hydrogen, a filter in said bore, a flexible fabric material in the form of a tube extending axially in said housing and defining a space communicating with said bore, said fabric material being resistant to hydrogen and bounding one axially extending surface of said storage material so that hydrogen can pass into and out of said storage material and so that said storage material can expand and contract radially into and out of said space.
Claim 2
Dependent Claim
118 words
A hydride storage for hydrogen comprising a rigid tubular housing containing a storage material therein having one closed end and an opposite end with an external connection, means defining a bore in said external connection and into said housing for the flow of hydrogen, a filter in said bore, a flexible fabric material in the form of a tube extending axially in said housing and defining a space communicating with said bore, said fabric material being resistant to hydrogen and bounding one axially extending surface of said storage material so that hydrogen can pass into and out of said storage material and so that said storage material can expand and contract radially into and out of said space.
