Document Type and Number:
WIPO Patent Application WO/2024/069801
Kind Code:
A1
Abstract:
The present invention is a control device for controlling operation of a water electrolysis stack, the device comprising: a measurement unit for measuring performance of the water electrolysis stack; a prediction unit for predicting the produced amount of hydrogen generated by the water electrolysis stack and the deterioration degree of the water electrolysis stack during a predetermined period by using the performance measured by the measurement unit and characteristics of the water electrolysis stack pertaining to how easily the stack deteriorates; and an operation condition determination unit for determining conditions for controlling operation of the water electrolysis stack on the basis of the prediction result from the prediction unit. Increase in lifecycle costs in a water electrolysis system in which water electrolysis stacks different in performance are present together can be suppressed thereby.
