Influence of Different Ship Harmonic Vibration Directions on Dynamic Response of PEMFC

Abstract

Abstract For the sake of study the applicability of PEMFC on ships, a three-dimensional single channel fuel cell model was established. The vibration load was loaded on the model through dynamic grid technology and user-defined function (UDF) method. The output voltage and reactive gas distribution of PEMFC loaded in different vibration directions were compared and analyzed. The results show that ship vibration will affect the transmission of components in the battery, resulting in incomplete electrochemical reaction and degradation of PEMFC performance. The influence of vertical vibration is greater than that of longitudinal vibration and lateral vibration.
