Abstract

A control device includes a step of determining a current command value to be applied to an electrolysis stack; and a step of determining a pure water adjustment amount command value for adjusting a pressure or/and a flow rate of water to be supplied to the electrolysis stack based on the current command value, and includes a step A of causing an actually measured value of the pressure or/and the flow rate to reach a second pure water adjustment amount command value (pure water adjustment amount command value w2) from a first pure water adjustment amount command value (pure water adjustment amount command value w1) before an actually measured value of a current applied from a power converter to the electrolysis stack reaches a second current command value (current command value c2) from a first current command value (current command value c1) when the current command value is changed from the first current command value to the second current command value that is a different value and the pure water adjustment amount command value is changed from the first pure water adjustment amount command value to the second pure water adjustment amount command value that is a different value.
