Abstract
An electrochemical cell is tebricated using the grinded leaves of Hibiscus rosa sinensis mixed with distilled water as the electrolyte. l't) obtain a cloc value to the available energy density, the cell is discharged at a current drain of I I m:\ and initial open circuit voltage of 0.7 V. An observation is made regarding the varir-tion ot voltage and current with respect to time, which is unlike the variation observed for any other electrochemical cell. The curve features and the power production for different combination (Series and Parallel) of cells have been studied.
