PROBLEM TO BE SOLVED: To curb hydrogen embrittlement of a hydrogen separation membrane at a low temperature in an apparatus for generating hydrogen. SOLUTION: Start-up control is performed according to a temperature of the hydrogen separation membrane at start-up in the apparatus for generating hydrogen having the hydrogen separation membrane to separate hydrogen from a reformed gas. When the hydrogen separation membrane is in a low temperature state, learn-burn is initiated for warming-up in a reforming equipment while curbing generation of hydrogen. At the time t1 when the temperature of the hydrogen separation membrane reaches a level of temperature, at which the hydrogen embrittlement dose not occur, a reforming starts. At this time, oxygen is supplied to hydrogen transmitted through the hydrogen separation membrane to burn it for further accelerating the warming-up. At the time t2 when the temperature reaches an operation temperature, the oxygen supply at purging side is stopped to stop the burning of hydrogen and the operation of the apparatus shifts in a steady operation. |
