520 3 _aVanadium Redox Flow Battery (V-RFB) with ability for decoupling power and energy, and theoretically having an infinite cycle life has made it as one of promising prospects for energy storage; both for stationary and mobility applications. Even so, low energy density of V-RFB has been a concern and research for embarking this technology is on the rise to expedite for massive commercialization. Poor energy density has caused available patented designs to be bulky in size thus requires further effort in optimizing the size especially for mobile applications. Literature has recommended that improving packaging of V-RFB design could be one of factors for optimizing the size and better output. Therefore, it is the purpose of this work to prove the hypothesis by improving the packaging of cell stack of V-RFB. Experimental data has been used as base in theoretically calculated using Faraday’s law of electrolysis. Better packaging has suggested a reduction of 75 % in cell stack size and 10.6 % of cell weight. Besides, this thesis also presents rhombus electrode compartment design for improving electrolytes distribution in vanadium redox flow battery (V-RFB) cell stack. The study involved the development of a mathematical model to address the effect of rhombus electrode compartment to avoid stagnant in the cell. In this case, three dimensional numerical model isothermal computational fluid dynamics (CFD) model of V-RFB is used to evaluate the effect of flow rate and flow field in different electrode compartment design. In this work, a rhombus-shaped electrode compartment is proposed and the effect of serpentine flow field is investigated. The performance of both rhombus-shaped and previous designed square-shaped electrode compartment are compared and with the former performed significantly better at all identified flow rates with respect to uniformity and reducing stagnant in cell stack
