AB  - Hydrogen storage using metal hydrides is one of the research hotspots in the field of energy storage. However, metal hydride powders are known to have low thermal conductivity, which causes significant temperature fluctuation and hinders further reaction, hence efficient thermal management is a must for hydrogen storage using metal hydrides. In this paper, based on the principle of entransy dissipation, the optimal profile of fin in a cylindrical reactor under steady-state conditions is deduced. The expression for the temperature distribution of the bed is also obtained, which could clearly account for the influences of multiple involving factors, such as fin thickness, fin spacing, and radius of reactor. Through simulation, the characteristic time of hydrogen absorption for reactor inserting the optimized fin, is shortened by 19.1 % compared with the conventional uniform thickness fin. The influence of the geometric parameters of storage reactor was further discussed. When the ratio of the inner and outer radius of the reactor is confined (rr/rt ≤ 2), linear thinning fin can be seen as a reasonable simplification of the optimized fin with comparable heat transfer enhancement effect. This study proves that the thermal management of metal hydride reactors, particularly those inserting high thermal conductivity materials like graphite, can be optimized quantitatively by entransy theory

AB  - High entropy alloys (HEA) represent a kind of materials with unique structural and functional properties, and have attracted wide attentions in many fields including hydrogen storage. Due to the huge diversity in the composition of HEAs, novel hydrogen storage materials with superior comprehensive performance are expected to be developed following the concept, with some notable progress made in the past decade. In this study, the present research status in HEAs for hydrogen storage is summarized from the aspects of theoretical guide, composition and preparation, microstructure and hydrogen storage properties. Moreover, the key issues in future development and possible application scenarios are analyzed.

AB  - Desalination is an important method to take full advantage of the sea water to produce fresh water. However, the systems or devices reported previously still have the limitations in the energy supply and portability when used in some specific application scenarios, such as island and remote coastal area. In this paper, a multi-function desalination system is proposed, which could provide fresh water, electrical energy, and even the cold energy based on the hydrolysis reaction of hydride and fuel cell water recovery. Besides, the system could be modified to increase the flexibility of the system operation to satisfy the various energy demands under different conditions. A lumped parameter model of the proposed system is developed to evaluate the system performance. The results show that the fuel cell helps to increase the absolute humidity of the wet air by 15.5% and to increase the water production by condensing the wet air by 1.8 times compared with simple water harvest from the ambient environment. The modified system demonstrates more stable performance of the water production than the original desalination system, which means that the modified system is less affected by the parameter variation. The maximum water production of the kW level system could achieve 11.10 kg/h. Comparing with the previous reports, the unit power consumption of the modified system could reach the lowest level (about 880 Wh/kg), showing the promising water production performance of the system developed in this work.
