HYDROGEN ACCUMULATOR Russian patent published in 2009 - IPC F17C11/00 

FIELD: mechanical engineering, gas distribution.

SUBSTANCE: invention relates to hydrogen power engineering, hydrogen accumulation, storage and release for use in vehicles and stationary power installations. A capillary bundle in the hydrogen accumulator is made as a monolith from capillaries of greater radius, capillaries of smaller radius are placed in the gaps between those of greater radius. The monolith end face surface is covered by a diffuser made from glass with the addition of 0.5-0.7% wt of Fe₂O₃ or NiO oxide, the capillaries end faces on the opposite monolith side are hermetically closed by glass caps. The greater capillary radius is related to the smaller one as 2.5:1. Capillaries are made from magnesiumaluminosilicate glass with the following composition: SiO₂ - 58-60% wt; Al₂O₃ - 23.5-25.5%; CaO+MgO - 14-17%; other components - 2% or from borosilicate glass with the following composition: SiO₂ - 72% wt; B₂O₃ - 25%; Al₂O₃ - 1%; LiO₂ - 0.5%; Na₂O - 0.5%; K₂O - 1%.

EFFECT: simplification of the hydrogen accumulator design, increase of hydrogen relative weight content, provides for multiple use of the accumulator along with its high reliability and service life.
