Study on Suitable Electrode for Energy Harvesting Using Galvanic Cell in Seawater
The present work aims to study galvanic cells using sea water as multicomponent electrolyte for energy harvesting. The electrochemical performances of Galvanic cells were carried out by measuring electric potentials by understanding the nature of conductivity of electrodes. Various combinations of electrodes like Graphite, Zinc, Copper, Aluminium, Brass and Iron were tested. A maximum yield of 1.1 V was obtained using the combination of Graphite–Iron as Cathode–Anode. The effect of sea water pH on electric potential was analysed using sea water from different parts of Bay of Bengal with varying depths. The electric potential obtained is further studied with respect to surface area of electrodes and galvanic corrosion of the coupled electrodes. The feasibility to apply Graphite–Iron as the electrodes to sea water battery for efficient energy harvesting was studied.
