Vanadium Oxygen Fuel Cell utilising high concentration electrolyte

We published an open acces article about a Vanadium Oxygen Fuel Cell (VOFC) utilising up to 3.6 mol/L high concentration vanadium electrolyte. Compared to Vanadium Redox Flow Batteries, VOFCs allow much higher theoretical energy density by the replacement of the positive electrolyte with an oxygen (air) electrode. The replacement allows the usage of higher concentrated vanadium electrolytes which further increases the theoretical energy density. We present here a VOFC with 3.6 M vanadium solution, which has a theoretical maximum energy density of 146 Wh/L.
