PROBLEM TO BE SOLVED: To provide a hydrogen separation method capable of efficiently separating hydrogen at a comparatively low temperature.SOLUTION: In a hydrogen separation method to separate hydrogen by a Pd-Ag alloy film,: Ag content in the Pd-Ag alloy film is 15-30 mass%; and a temperature at separation treatment is lower than 300°C and is the temperature where the hydrogen transmission flux of the Pd-Ag alloy film becomes 80% or more of the hydrogen transmission flux of hydrogen at 400°C. It is preferable that the primary side pressure Pof the Pd-Ag alloy film at the separation treatment is 100-1,000 kPa and P/Pis 1.4-10. |
