ACCUMULATOR FOR HYDROGEN STORAGE IN BOUND STATE AND ACCUMULATOR CARTRIDGE

摘要

FIELD: energy.;SUBSTANCE: invention relates to hydrogen power engineering and can be used for storage, transportation and distribution (supply) of hydrogen in fuel cells and other power plants. Hydrogen accumulator structure is based on the concept of modular implementation of a hydrogen accumulator in the form of a system of easily replaceable during operation cartridges containing hydrogen in the bound state in a hydrogen-saturated film coating applied on a metal foil tape, which can be folded then into a spiral or another form with a shape providing high degree of compaction. For fixation of the cartridges a system of heat exchange elements with bee cells geometry is used, and a device for extracting hydrogen of the accumulator has a system of needles/knives for depressurization of charged (hydrogen-charged) cartridges after their initial loading into the accumulator. To obtain the possibility of using fast-response time hydrogen thermal desorption modes as the foil material selected are metals or alloys with high ohmic resistance, ends of the foil are connected with electric contacts on the metal end of the cartridge connected with a controlled voltage source. Fast-response time hydrogen thermal desorption is performed by ohmic heating the foil with high resistance, that provides new possibilities for programming hydrogen release parameters.;EFFECT: technical result of using the invention are elimination of explosion hazard in emergency situations, higher bulk density of hydrogen in the accumulator and improved operating performances, including minimization of hydrogen release transient modes time down to 0,1 sec, as well as of pressure level in the accumulator at hydrogen supply to consumers.;8 cl, 3 dwg
