In this article we are introducing a new cell composed of electrodes of Graphite –Mg and electrolyte of HCl- KMnO4 . Along this topic we are trying to discuss the effect of concentrationchanges of the electrolyte and temperature of the cell as well as surface area effect of each one ofthe electrodes. To estimate the usefulness duration of the cell, all of the reactions have beenkinetically analyzed. After making some changes in the structure of the cell and differing theelectrode type and replacing some metals like Cu and Zn instead of Mg, the produced powers havebeen compared. From the experimental observations and theoretical analyses, it is found out that using other metals instead of Mg decreases the produced power. Finally this kind of cell is compared with fuel cell.
