One of the major challenges in using hydrogen vehicles is how to store and release hydrogen in the car. Following this challenge, it seems that the method of using metal hydride tanks will have a better future. In addition to these tanks, the use of methods for cooling the tank is very important. The new idea of using phase change materials can solve the problem of cooling and thermal management of metal hydride tanks. It may also be advisable to use a variety of heat exchangers to improve heat transfer between the metal hydride tank and the phase change materials.
On the other hand, the phase change material acts in such a way that the heat is not well transferred to different areas and they have a low heat transfer coefficient, especially when they are in the liquid state. Therefore, to improve the design of the tank, the use of fins can transfer heat to different areas of the phase change material.
In this study, a metal hydride tank with an extended surface was designed to store and release hydrogen, and then the performance of the tank was investigated with the presence of phase change material by ANSYS Fluent simulation software using computational fluid dynamics methods, and the effect of the presence of fins for better heat transfer in the tank has been investigated.
Examining and observing simulated cases, it is clear that simply increasing the heat transfer and increasing the number of fins does not achieve the desired result.
