“…Several types of metal foams were integrated into the MH to improve the hydrogen storage performance. 5,[38][39][40] Furthermore, metal foams were also integrated into phase change material (PCM) to improve thermal storage performance. 41,42 This combination of PCM and metal foams has rarely been applied to MH reactors.…”

“…The high strength structure is also one of the main characteristics that make these solutions good options for increasing the effective thermal conductivity of the metal hydride bed. The most common material is aluminum foam, which combines lightness and high thermal conductivity [ 76 , 77 , 78 , 79 , 80 , 81 , 82 ].…”

The efficient operation of a metal hydride reactor depends on the hydrogen sorption and desorption reaction rate. In this regard, special attention is paid to heat management solutions when designing metal hydride hydrogen storage systems. One of the effective solutions for improving the heat and mass transfer effect in metal hydride beds is the use of heat exchangers. The design of modern cylindrical-shaped reactors makes it possible to optimize the number of heat exchange elements, design of fins and cooling tubes, filter arrangement and geometrical distribution of metal hydride bed elements. Thus, the development of a metal hydride reactor design with optimal weight and size characteristics, taking into account the efficiency of heat transfer and metal hydride bed design, is the relevant task. This paper discusses the influence of different configurations of heat exchangers and metal hydride bed for modern solid-state hydrogen storage systems. The main advantages and disadvantages of various configurations are considered in terms of heat transfer as well as weight and size characteristics. A comparative analysis of the heat exchangers, fins and other solutions efficiency has been performed, which makes it possible to summarize and facilitate the choice of the reactor configuration in the future.

“…Several groups of researchers have proposed to integrate fins with different-shaped or heat pipes into the tank to increase the heat transfer area [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Others have attempted to maximize the thermal conductivity using metal foams [30,31] and adding expanded graphite [32,33] or a copper matrix [34]. In all of these studies, an external source of heat was needed to power the discharge process.…”

Parametric Optimization of a Truncated Conical Metal Hydride Bed Surrounded by a Ring of PCM for Heat Recovery

Metal hydride (MH) hydrogen storage needs an external heat source to release the stored hydrogen. To enhance the thermal performance of MHs, the incorporation of phase change materials (PCM) is a way to preserve reaction heat. This work proposes a new MH-PCM compact disk configuration (i.e., a truncated conical MH bed surrounded by a PCM ring). An optimization method is developed to find the optimal geometrical parameters of the MH truncated cone, which is then compared to a basic configuration (i.e., a cylindrical MH surrounded by a PCM ring). Moreover, a mathematical model is developed and used to optimize the heat transfer in a stack of MH-PCM disks. The optimum geometric parameters found (bottom radius of 0.2, top radius of 0.75 and tilt angle of 58.24) allow the truncated conical MH bed to reach a faster heat transfer rate and a large surface area of higher heat exchange. Compared to a cylindrical configuration, the optimized truncated cone shape enhances the heat transfer rate and the reaction rate in the MH bed by 37.68%.
