![عکس صفحه اول مقاله: Development of flow field design of polymer electrolyte membrane fuel cell using in-situ impedance spectroscopy Development of flow field design of polymer electrolyte membrane fuel cell using in-situ impedance spectroscopy](/preview/png/1278921.png)
The design of a flow field channel of a polymer electrolyte membrane fuel cell (PEMFC) was investigated by computational fluid dynamic (CFD) simulation and in-situ three-channel impedance spectroscopy. To investigate the efficiency of the in-situ three-channel impedance spectroscopy method, it was adopted with a heterogeneous stack, which was composed according to three different types of flow field design. The in-situ three-channel method proved its validity by showing corresponding result with that obtained from the experiments and CFD simulation at the same experimental condition. This study demonstrates that a heterogeneous stack and in-situ three-channel impedance spectroscopy are powerful tools for predicting and analyzing the performance of a fuel cell stack.
