Although the thermal coupling between metal hydrogen storage and fuel cells can effectively utilise the MH hydrogen absorption as well as the waste heat generated during the operation in a supplementary way, it also puts forward greater requirements on the structure of the thermal management system and the control method of the system.
Electrochemical hydrogen storage is the most efficient technique amongst the gaseous and liquid hydrogen storage. On the electrochemical breakdown of an aqueous solution, atomic hydrogen adsorbs onto hydrogen storage material (Gholami et al., 2017). Volmer and Tafel's reactions are involved in the electrochemical hydrogen sorption process.
The solid-state hydrogen storage device and fuel cell in the cooling circuit in the series structure shown in Figure 2 a may lead to a deviation in the fuel cell’s temperature from the optimal operating temperature point and reduce the fuel cell’s efficiency [ 19 ].
On the other hand, even though the hydrogen storage system can be considered a single energy storage solution, it has been divided into two conversion systems (e.g., electrolyser and fuel cell) plus one storage (e.g., hydrogen tank) to evaluate the power and energy decoupling nature of this solution.
