<P>PROBLEM TO BE SOLVED: To readily and reliably detect a failure of a relief valve, prevent the relief valve from wastefully discharging hydrogen as soon as possible, and efficiently perform economical electrolytic treatment. <P>SOLUTION: A method for controlling a high pressure water electrolysis system 10 includes: a pressure rising time calculation step of calculating a pressure rising time in which the pressure of hydrogen rises to a preset pressure of a back pressure valve 36; a pressure measuring step of measuring the pressure of hydrogen by a pressure gauge 38 disposed upstream of the back pressure valve 36; a pressure comparison step of comparing the measured pressure of hydrogen with the preset pressure of the back pressure valve 36 after a lapse of the calculated pressure rising time; and a system stopping step of stopping the system when the compared pressure of hydrogen is lower than the preset pressure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
