Abstract

A simulator of an embodiment is an electrolysis device simulator configured to simulate, by computation, the performance of a first electrolysis cell stack including one or more electrolysis cells each including a cathode configured to perform a reduction reaction and an anode configured to perform an oxidation reaction. It includes an arithmetic unit configured to perform an arithmetic operation using a first variable group representing at least one of flooding and salt precipitation in the first electrolysis cell stack, in a computational algorithm implemented in the simulator of the embodiment.
