摘要：Abstract Most of the energy used in the world is obtained from fossil fuels. Some reasons like air and environmental pollution, high-energy costs and depletion of fossil fuels, increased the importance of studies about new and renewable energy sources in the world. Among the new and renewable energy sources hydrogen has great importance. Hydrogen which exists in great amounts in the world has the highest energy content per unit mass. The subject of fuel cells is one of the main research topics in hydrogen energy. The purpose of this study, is to analyze the performance of fuel cells. to do this a model of fuel cell is created in Finite element method program. membrane thickness and electrolyte type of fuel cell is selected as variables.
