Modeling and control strategies for solid-state hydrogen storage system in fuel cell

Abstract

Given the disadvantageous factors of the currently prevalent high-pressure hydrogen cylinder storage technology for providing hydrogen to proton exchange membrane fuel cell (PEMFC), such as bulky systems, significant energy losses, and high costs, this study adopts a novel and efficient solid-state hydrogen storage technology as the hydrogen supply method for PEMFC. Through the design of the topological structure of the metal hydride hydrogen storage system, a simulation model of the metal hydride hydrogen storage system is built on the MATLAB/Simulink platform based on this structure. The research focuses on designing corresponding control methods for the hydrogen release process of the solid-state hydrogen storage device. The simulation results demonstrate that the designed controller achieves rapid response within 15 seconds, exhibiting excellent dynamic performance, and effectively realizes the objective of supplying hydrogen to the fuel cell system rapidly and stably.
