Research Interest:
Metal hydrides can offer higher volumetric hydrogen storage density, superior cyclic stability and prominent safety, facilitating highly promising solutions for clean energy applications in the context of carbon neutrality. Although metal hydride reactor (MHR) plays a critical role in determining its overall heat & mass transfer and hydrogenation/dehydrogenation rates, the traditional structural design & optimization of an MHR is still confined to some limited regular geometric shapes with a low degree of freedom. In this study, a Topology optimization-Guided, dual-domain heat transfer metal hydride reactor (DDR@TO) is proposed, which integrates heat transfer fluid channels with thermally conductive fins and is supported by a self-developed high-fidelity kinetic model. Through macroscopic-scale regulation of key geometric parameters—such as the aspect ratio, radius of heat transfer channel, and fin volume fraction—combined with microscopic-scale topological parameters, the effects of structural variations on hydrogen absorption/desorption behavior are comprehensively evaluated. Furthermore, response surface methodology is employed to analyze the multifactorial interactions of operational parameters on reactor performance, providing quantitative insights for sensitivity identification and operational optimization. A unified simulation framework applicable to various hydrogen storage material systems is also established, validating the proposed reactor’s structural generality and performance adaptability. This work offers both theoretical foundation and practical guidance for the optimized design and mechanistic understanding of metal hydride hydrogen storage reactors.
