Hydrogen fuel is the main source of energy production in fuel cells which can play an important role in future of world energy. The best and most economical way to produce hydrogen as a clean fuel alternative to fossil fuels is methane steam reforming. Methane steam reforming was originally modeled in this article, based on the results of research presented in the various authorities, to investigate the process of reforming methane in the presence of water vapor in membrane reactors and compare the performance of this type of reactor in the same condition was common with conventional reactors. The results of modeling showed that methane conversion rise from 0.275 in conventional reactors to 0.434 in membrane reactors with an acceptable error 1.66% . This is due to using of membrane reactors technology in the process that increases the separation of hydrogen and the efficiency of the process.
