Abstract
Fuel cell is expected as the future power generation source. However, the formation method of hydrogen as the fuel of fuel cell is not established. In this study, equilibrium calculation was performed for the purpose of investigating the steam reformation characteristic of various fuels, methanol, natural gas and octane. In calculations the effects of temperature and S/F (Steam/Fuel) on hydrogen formation were examined by considering the amount of hydrogen and byproduct formation, and the enthalpy before and after the reformation.
