Abstract: Seawater battery is one of the green electricity sources to fulfill energy need for electrical equipment, especially in the coastal area and fishing activity .A survey was conducted among fishermen in which it was found that small scale fishermen uses lead acid battery and fuel cell in order to charge the mobile phone and glow the fishing lights. But major drawback of lead acid battery and fuel cell is that the maintenance cost is higher which is difficult for them to afford. Seawater is one most available sources all over the world and it is of no cost, hence a seawater battery is designed.Thispaper aims to study galvanic cells using sea water as 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. The effect of sea water pH on electric potential was analyzed using sea water from different parts of Bay of Bengal with varying depths. 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 for a single cell. Further, we developed a working prototype for 16 cell. It generates a voltage of 12 V and 20 mA. Since the output current obtained was not as desired so we added a current amplification circuit and obtained a maximum current of 300mA from 20mA.
