A hydrogen storage reactor based on phase change material and heater cooperative temperature control

Abstract

This invention relates to the field of solid-state hydrogen storage technology and discloses a hydrogen storage reactor based on synergistic temperature control of phase change material and heater. The reactor includes an outer cylinder, a cap, a hydrogen inlet / outlet, a guide pipe, and multiple hydrogen storage unit modules. The cap is located at the upper end of the outer cylinder, and the hydrogen inlet / outlet is located at the top of the cap. The guide pipe communicates with the hydrogen inlet / outlet. Multiple hydrogen storage unit modules are disposed within the outer cylinder, and from the inside out, each module includes a filling zone A, a filling zone B, and a filling zone C. The filling zone A is filled with a hydrogen storage metal material, which has a porous structure and a circular rib structure formed on its outer periphery. The filling zone B surrounds the filling zone A and is filled with a phase change material. By constructing a layered coupling structure between the filling zones A, B, and C, a synergistic effect of passive heat storage and active heat replenishment is achieved.
