Our experiments reveal that an O2 deficient anodic environment can enhance the H2 production along with a prolonged discharge time. It has also been witnessed that gaseous byproducts of chemical reactions occurring in electrochemical systems can be utilized for renewable energy generation.(28) A possible idea made by the authors here is the utilization of generated H2(g) while exploiting the cell for maximum discharge capacity (discharge time in a given mass of Zn).
