COMPACT SYSTEM FOR STABILIZING HYDROGEN PRESSURE IN PORTABLE POWER SOURCE BASED ON CHEMICAL REACTOR Russian patent published in 2020 - IPC H01M8/06 C01B3/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to stabilize hydrogen pressure in portable power sources including a chemical hydrogen source and an electrochemical generator. Feed buffer is connected in series with a chemical hydrogen source in a portable source of ethane to the hydrogen gas line. Storage buffer used is a thin-walled polymer vessel with a screwed cover, which is equipped with a sealed nozzle, outside the cover the union ends with a threaded connection for connection of a gas threaded fitting, and opposite end of nozzle has cylindrical place with groove for fixation and sealing of elastic membrane. Elastic membrane divides the total volume of the vessel into two compartments of variable volumes. On the shell of the vessel there are outlet and inlet valves, pressure in compartment with hydrogen is determined by pressure in gas main line of hydrogen. To adjust the pressure inside the polymer vessel there are inlet and outlet valves, or holes with diameter from 1 mm to 3 mm with smooth edges. At abrupt jumps of hydrogen pressure in the gas main the elastic membrane in the buffer-accumulator provides the required inertia of change of volumes of compartments and limits pressure drops of hydrogen in gas main line of the power supply source in safe limits.

EFFECT: technical result of invention is smoothing of non-uniformity in generation of hydrogen and maintenance of constant level of power of portable power supply.
