Abstract

In one approach, in a diagnosis method of an electrolysis unit (2), an impedance of the electrolysis unit (2) is measured in each of a first frequency range (ΔF1) and a second frequency range (ΔF2) lower in frequency than the first frequency range (ΔF1). In the diagnosis method, a resistance value of each of a first resistance component (R1) in which influence on the impedance becomes dominant in a first frequency range (ΔF1) and a second resistance component (R2) in which influence on the impedance becomes dominant in a second frequency range (ΔF2) is calculated based on measurement results of the impedance, and degradation and operation of the electrolysis unit (2) are determined based at least on a calculation result of each of the resistance values of the first resistance component (R1) and the second resistance component (R2).
