redox flow batteries are similar to fuel cells
14 Question (2 points) Redox flow batteries are similar to fuel cells in that the reactants are continuously delivered to an electrochemical cell from large storage tanks. In the cell shown here, an ion exchange membrane separates the reactants from each other; the arrows indicate the direction of flow for the reactants. The reactions in one type of redox flow battery can be diagrammed as follows: C(s) IV2(aq, V3"(aq) IVO'(aq). Vo?'(aq) IC(s)...
