| Summary: | The fact that the industrial factor progresses to the point where the fossil energy sources such as petroleum natural gas, which constitute a large part of human’s energy needs, move to the point of decreasing and exhausting day by day, and the increasing damage caused by the resources used for energy production leads the scientists to alternative energy sources. Fuel oil application, one of these alternative energy sources, draws attention. In this study, PEM fuel cell stack is analyzed by numerically. Two PEM fuel cells are turned into stack, each of which has 5.4 cm2 active area, by connecting in series. Reactants of anode and cathode flow direction is preferred parallel. PEM fuel cells are accepted as operating conditions of 70oC and 1 atm. Power values of this designed stack is calculated and presented in the study. Electrical power values of one and two PEMFCs are presented in graphics.
