1. An electrolysis system comprising:
an electrolyzer in which an anode and a cathode are overlapped one another having a diaphragm interposed therebetween; and
a liquid surface level control unit that is operated when an electric conduction to the electrolyzer is stopped to adjust a liquid surface level of an electrolytic solution in the electrolytic cell,
wherein a time duration during which the liquid surface level control unit is operated is more than 0% and less than or equal to 20% of a time duration during which the electric conduction is stopped which is taken to be 100%,
the liquid surface level control unit adjusts the liquid surface level according to the time duration during which the electric conduction is stopped, and
the liquid surface level control unit adjusts the liquid surface level according to an electric resistance value between the anode and the cathode.
