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 that the difference between the maximum and the minimum temperature was 6℃ under adiabatic boundary condition, and that the temperature at cathode channel outlet was higher than that at anode channel outlet caused by the electro-osmosis flow of water.
