In this study, the effects of operating parameters including temperature, relative humidity, hydrogen pressure and membrane thickness on hydrogen crossover have been investigated. It is found that hydrogen crossover increases proportionally to the increase in both temperature and relative humidity for all membrane samples. The increase in hydrogen crossover is also observed with increasing hydrogen pressure. A comparison among all of the operating parameters on hydrogen crossover is analyzed using a multiple linear regression analysis. The results indicate that the main factors causing increase in hydrogen crossover are in the order of membrane thickness, hydrogen pressure, RH, and temperature.
