Numerical Study on Characteristics of Hydrogen Production by High Temperature Steam Electrolysis (HTSE)

The characteristics of hydrogen production in high temperature steam electrolysis (HTSE) have been numerically analyzed in a two-dimension with the Comsol multiphysics. The main parameters for the calculation are appllied voltage and ASR (Area Specific Resistance). The results showed that thermal neutral voltage was 1.2454 V and a mean temperature in cell was decreased by less than 1.2454 V and it was increased by more than 1.2454 V. This means that the mean temperature in cell is not increase monotonously with increasing the applied voltage. The mean temperature and the rate of hydrogen production in cell were decreased with increase in ASR.
