Precise estimation of temperature distribution in enlarged water electrolysis cell is a key issue related to its performance and durability. In this study we numerically simulated the water electrolysis cell within two-dimensional region. The simulation is based on conservation equations, equivalent electric circuit and the hydrogen solubility process, which is formulated from the phase equilibrium theory and the Soave-Redlich-Kwong equation of state with mixing rule. As result, we found out that the difference between the maximum and the minimum temperature was 2℃ under the constant temperature boundary condition, and that hydrogen was produced as the dissolved species in case of small electrolysis ratio.
