Abstract: In the era of this modern technology, Fuel Cell (FC) is the most effective and continuous power generation system. A FC is a system where chemical energy is converted to electrical energy through an electrochemical reaction of hydrogen with an oxidizing agent such as oxygen. The author previously proposed the new PV generation system where surplus electric power is used for electrolysis of water to generate hydrogen, which is used to convert into electricity by FC at nighttime or in the bad weather. In this system, oxygen is produced as a by-product in the process. Therefore, this paper investigates the use of this oxygen for the power generation, which makes the system more effective than the old system of FC with the air. The experiment of using air and oxygen shows that when oxygen is used, FC efficiency increases by 12% and the output power is increased twice as much as of air. The latest FC technology, Polymer Electrolyte Fuel Cell (PEMFC) is used for conducting the whole experiment for getting the best result.
