One form of energy that is widely used is electrical energy. Electrical energy problems in Indonesia, especially in remote areas and when the emergency conditions become one of the things that have not been solved until now. In this study, alternative energy sources will be created using metal-air fuel cells that can be used to supply small and medium-scale electricity needs. The metal-air fuel cell works by electrochemical principle, which uses the difference in the standard cell potential of a metal to generate electricity. Metal-air fuel cells have three main components: metal anodes that will oxidize to produce electrons, electrolytes that mediate the displacement of hydroxide ions, and the cathode that breaks oxygen from the air with the addition of electrons into hydroxide ions. With electrochemical principle, this system has higher efficiency compared with combustion system because chemical energy is converted directly into electrical energy. In addition, the system uses cheap, safe, and easily obtainable metals such as aluminum, zinc, ferrum, or magnesium. In this research will search the optimized cell from many configuration, to obtain better performance such as with the modification and selection of metal and appropriate electrolyte modification. Once the system prototype for any optimization is made, testing the characteristics of the system will play an important role. The prototype will test the current value that provides optimal power of the system by varying the load, then how long the system can provide constant power. Then the characterization results will be used as material to design the whole metal-air fuel cell system.
