Hydrogen formation and purification by methanol steam reforming and the Pd/Ag hydrogen separation membrane were investigated experimentally. Hydrogen permeation rate increases with increasing total pressure of the reformed gas, while it is independent from methanol flow rate. When the methanol flow rate is increased, the hydrogen concentration boundary layer over a separation membrane become thinner and the permeation rate of hydrogen increases, which recovers the decrease in the permeation rate of hydrogen due to a decrease in the hydrogen partial pressure in the reformed gas. These tendencies are estimated well by taking into account of the decrease in the partial pressure of hydrogen at the separation membrane due to the hydrogen permeation.
