PKL electricity- A new idea on Zn/Cu based electrochemical cell

Renewable Energy

A PKL module has been designed and fabricated in this article, which is Zn/Cu based. The PKL extract was used as an electrolyte for this module. It has been studied the open circuit voltage, short circuit current, maximum power, load power and internal resistance. The maximum open circuit voltage was 4.8 volt and the minimum open circuit voltage was 3.6 volt. So that the difference was 1 volt. The maximum load voltage was 2.7 volt and the minimum load voltage was 2.5 volt. So that the difference was 0.20 volt. The maximum short circuit current was 1.4 mA and the minimum short circuit current was 1.00 mA. So that the difference was 0.40 mA. The maximum load current was 1.3 mA and the minimum load current was0.80 mA. So that the difference was 0.50 mA. The maximum power was 6.6 mW and the minimum power was 4.0 mW. So that the difference was 2.6 mW. The maximum load power was 3.5 mW and the minimum load power was 2 mW. So that the difference was 1.5 mW. The maximuminternal resistance was 4.1 ohm and the minimum internal resistance was 3 ohm. So that the difference was 1.1 ohm. This work may be the guide line for practical utilization of PKL electricity.
