A study on pkl electrochemical cell for three different conditions

Abstract

It has been conducted this research work to measure the short-circuit current (Isc) and capacity (C = AH) for different conditions of the PKL (Pathor Kuchi Leaf). The copper and zinc plates have been embedded between the two ends of the PKL for three different conditions like fresh leaves, dry leaves and living leaves to make PKL electrochemical cells. The plates were kept tightly binding by plastic clips. A sophisticated multimeter was used to measure the short-circuit current (Isc). The short-circuit current was recorded after 12 h interval. It was seen that the obtained maximum current was 0.7 A for living PKL tree and the minimum current was recorded for dry PKL about 0.10 A for dry PKL. The variation between maximum and minimum short-circuit current difference is for dry PKL is 0.14 A, for fresh PKL is 0.10 A and for living PKL tree is 0.00 A. The maximum capacity was 67.2 AH for living PKL tree and the minimum capacity was 2.16 AH for dry PKL. This type of works has been conducted by us for the first time in Bangladesh. It will help the poor for practical power applications with solar photovoltaic systems. There are some differences from the SPV (Solar Photovoltaic System). The SPV system did not work at night and rainy season. But these PKL power woks equally both day and night time. Furthermore, the PKL power technology is new and innovated technology in Bangladesh whereas the SPV device was innovated by a Russian scientist. For better performance of the PKL electrochemical cell, Some Performance and operation characteristics of the PKL electrochemical cell like input–output curves, efficiency curves, heat rate and incremental curves have been conducted. Finally, the performance of the PKL electrochemical extract cell has been studied by magnetic stirrer with hot plate. It is found that the performance of the PKL cell increases after making oscillation for PKL filtered extract by magnetic stirrer with hot plate.
