This research mainly utilizes the ESI-CFD software to analyze the flow fields, heat and electrochemical reaction for a single cell within the proton exchange membrane fuel cell (PEMFC). Through creating the whole module, the changes of electrical current density under various voltages and make comparison with actually measured values can be explored. It is hoped that by using this evaluation, we can simulate the result accuracy available for subsequent reference for the design of flow fields can be simulated.
Within the research, the reaction areas of a single cell are and , on totally two kinds of dimensions. is mainly used to examine the error between simulation and experiment. Through this, it is available to examine the simulated plausibility. is the parameters created in accordance with the simulate result from model of . It is purely adopt the emulation ways to explore the possible performance influence caused by parameter changed. This part retrieves examples form some scientific literatures. It focuses on the phenomenon created by PEMFC experiment to serve as the reference for parameter changes under simulate, such as flow channel grouping arrangement and increasing back pressure. Through this, we can determine whether the simulate results well comply with those of past scientific literatures. Also, it is available to examine whether our results can comply with the existent trends
