The present study establishes a simulation model of a metal hydride hydrogen storage system on the MATLAB/Simulink platform and achieve the objective of continuously and stably supplying hydrogen to the fuel cell system by controlling the hydrogen release process of the solid-state hydrogen storage device. The Authors, published by EDP Sciences.
Therefore, thermal management technologies are essential to enhance the performance of hydrogen storage reactors. This study systematically assessed the thermal and hydrogen storage performance of metal hydride hydrogen storage reactors, aiming to provide a theoretical basis for the optimization of thermal management technologies.
For the solid-state hydrogen storage device designed in this paper, the control objectives are the hydrogen supply rate, internal pressure, and temperature of the hydrogen storage tank. The control primarily consists of three parts, corresponding to actuators including the hydrogen flow valve, flow divider valve, and circulating pump.
These technologies enhance the reactor's hydrogen storage and heat transfer efficiency by increasing heat transfer area and optimizing temperature distribution. However, these methods also have certain limitations.
Hydrogen can also be stored on the surfaces of solids (by adsorption) or within solids (by absorption). HFTO conducts research and development activities to advance hydrogen storage systems technology and develop novel hydrogen storage materials.
Since the hydrogen storage tank requires excellent heat transfer capability to facilitate the absorption/release of hydrogen reactions, this study adopts a liquid forced convection heat exchange method with higher heat transfer efficiency for the design of the hydrogen storage tank's thermal management system.
The two–tank system uses a single network of heat transfer fluid (HTF) that flows between a cold storage tank and a hot storage tank. During charging, HTF flows from the cold tank through a
