Using our model, we investigated the temperature and cell performance of the 100kW class stack. In the 100kW class stack test, an anomalous cell voltage profile was observed. This result was similar to the 100kW class test result, and suggests that non-uniformity of internal resistance could be one of the reasons for cell voltage deviation. In the future, we will analyze unusual operating conditions or abnormal stack using the model that we have developed. Electric resistance of separator Fig.
