The objective of this research for studying about alternative energy which is clean and environmental friendly for reducing an air pollution which affects the people life in the present. This research study on the performance of the micro direct ethanol fuel cell (Micro-DEFC) for the portable electronic device. It is also to study the consumption of ethanol fuel which affect on the electric current density production. The cell performance is specified in the terms of cell voltage and power of the cell at several conditions. The results indicated that the increasing of concentrations of ethanol by volume, fuel at the reaction site is increased with the electrochemical rate is also increased but when it is reached the saturation point are gently drop. From the average experimental data revealed that the maximum current production, maximum voltage and maximum power density of fuel cell are 18.8 mA, 0.96 V and 18.2 mW, respectively. They are occurred at the ratio of ethanol equal to 13 milliliters mixed 60 milliliters of pure distilled water and the cell operating temperature at 49 to 50 °C intense 1 atm of pressure. From the calculations show that the increasing ethanol, the operating temperature of the fuel cell, the electrical current production and electrical power density production are also increased. On the other hand, the electrical potential of the fuel cell and the efficiency of the fuel cell are noticeably reduced.
