A container for use in hydrogen transfer includes structural tubular
members and perforations for fluid communication with a central passage
covered with a film that is selectively permeable to hydrogen, but not to
other gases. The tubular member walls comprise a sturdy material to fix
the hydride powder, preventing it from shifting within the container. The
hydrogen flow, when being absorbed or desorbed by the metal hydride, will
pass through the film both as it is absorbed in the hydride material and
also after it is desorbed to pass into the central passage.
Simultaneously, the tubular member material, acting as a flexible cover
or support for the film, retains contaminant gases within the conduit
passage, but permits hydrogen to flow therethrough. Alternatively, a
flexible conduit may be interspersed within selected ones of the
longitudinal structural members, and hydride material may be packed
within the springs, which provide for expansion protection.
