    When two conductors, namely Cu and Zn are connectedvia an electrolyte solution forminga circuitof cell voltaic, a potential difference arises as a result of chemical reactions in both electrodes. Because reduction reaction performs at a positive electrodeandoxidation reaction occurs at a negative electrode (Zn), electrons flow from Zn to Cu. This research clarifies performance of pineapple (Ananas comosus L. Merr) as an electrolyte solution. Cell voltaic design modificationis carried out by varying an area of plate electrodes, electrode distance and volume of electrolyte solution. The experimental results showed the voltage is independent on the variables. This is an opportunity to reduce the dimension of the cell voltaic. Observation of cell voltaic performance showedthat the current decrease as a polynomial function of time for the filtered or notfiltered of electrolytesolution. Finally a resistance value will be defined by an atreatment of electrolyte solution. Keyword: potential difference, cell voltaic, pineapple, Cu, Zn
