A Fabrication of Galvanic Cell from Pineapple Peel Residue in Agricultural Industries

Abstract

In this research, we present a fabrication of an electric generation experimental kit which is comprised of pineapple peel residue from agricultural industries. Juice from squeezing pineapple peel was used as electrolyte of a galvanic cell. Sufficient acidity of the juice could activate electrochemical reaction in the galvanic cell kit using a zinc plate and copper plate as electrodes. During the experiment, adjustable distances between the two electrodes were controlled to obtain maximum output voltage. It has been already known that a galvanic cell with a lower distance between electrodes could provide higher output voltage but both electrodes could not touch each other. Experimental results from controlling distances between the 2 electrodes showed that the galvanic cell kit could provide high output voltage of 1.00 V which was able to apply in electronic devices.
