The membrane electrode assembly is virtually divided into a plurality of small regions arranged along the flow of reactive gases. A current density 132 and a transfer amount 136 of water in an n-1 region are calculated referring to the maps defining a relationship between a power generation environment and a current density and a relationship between the power generation environment and a transfer amount of water, on the basis of power generation environments 122 and 128 transmitted from a pre-stage. Consumption amounts 138 and 146 of the reactive gases are calculated from the current density 132. A power generation environment transmitted to an n region is calculated by reflecting the consumption amounts 138 and 146 of the reactive gases and the transfer amount 136 of water (140, 144, 148, 150). Power generation environments and power generation states are sequentially predicted as to all the small regions. |
