Tang et al. [30] found that the temperature of flow field plate and inside had a more frequent fluctuation. Therefore, we establish a temperature and heat transfer (T&HT) modelaccording to thermodynamics and electrochemistry. In addition, we prove that the T&HT model has better capture dynamic effects under the conditions of symmetric humidification and asymmetric humidification. Furthermore, we demonstrate that asymmetric humidification can effectively improve PEM fuel cell system efficiency and performance. Although many investigations have been done on PEM fuel cell, few studies have been discussed the effects on the hydration of the membrane, humidification and dynamic temperatures in asymmetrical humidification. This paper not only theoretically studies the influence of dynamic temperature on the performance of fuel cells, but also can reduce the occurrence offlooding by controlling the temperature. Apart from that, the hydration of PEM is obviously promoted by the increase of operating temperature and cathode humidification, but theeffects of anode humidification on the hydration are faint and the elevator of relative humidity leads to the increase of voltage. Therefore, the study of dynamic temperature has important theoretical and practical significance. Above all, this method makes the calculation of internal water content closer to the actual experiment to improve the accuracy of the calculation. This method can be used in other heat-related calculations.
