In this work, the optimum flow rate and current density of Nafion 117 membranes were examined and compared using 5cm<sup>2</sup> and 25cm<sup>2</sup> size of interdigitated flow field to operate VRFB at maximum efficiencies and discharge capacity. During discharge, flow field 25cm<sup>2</sup> showed the highest discharge capacity of 367.5mAh at 10mAcm<sup>-2</sup> as compared to 5cm<sup>2</sup> flow filed which gave 221.9mAh. For battery efficiencies, three different parameters showed significant effects on different size of interdigitated flow field. 25 cm<sup>2</sup> size of interdigitated flow field gave higher efficiencies than 5.0 cm<sup>2</sup> up to 98%. This research offers fundamental understandings that bigger active area is needed to fully utilize the performance of VRFB.</p>}, number={2}, journal={Journal of Advanced Research in Fluid Mechanics and Thermal Sciences}, author={Hairul Mardiah Hamzah and Teo Ming Ting and Ebrahim Abouzari-Lotf and Roshafima Rasit Ali and Saidatul Sophia Sha’rani}, year={2022}, month={Jan.}, pages={128–138} }
