Summary:

Nowadays, proton exchange membrane (PEM) fuel cell is widely seen as a promising energy conversion device especially for transportation application scenario, due to its high efficiency, low operation temperature and nearly-zero road emission. Modeling and simulation is of significant importance to help cast light on the complicated physiochemical phenomena and provide optimization suggestions and strategies, e.g. on structure design. PEM fuel cell models have been developed based on different dimensions including 1D, 2D, 3D and intermediate combinations in between (e.g. "1+1D") during the past decades. 1D model benefits from plentiful assumptions and gains excellent calculation speed. On the other hand, 3D model has great advantage on obtaining comprehensive information inside the cell. For macro-scale modeling work, one compromise aiming to realize both acceptable computation speed and reasonable reflection of cell operation state is to simplify the membrane electrode assembly (MEA). Therefore in this study, a "3D+1D" model is developed in which the 3D domain contains flow field and gas diffusion layer (GDL) of cathode side. The remaining part of MEA and the anode side are treated as 1D domain. The model considers two-phase flow in both 3D domain and 1D domain, which is correlated at the interface. In addition, catalyst layer agglomerate model is also incorporated. Adopting this "3D+1D" model, large-scale simulation regarding computational domain with practical active area (hundreds of cm-2) and full configuration of bipolar plate is conducted. Comparisons among simulation results of the "3D+1D" model, the complete 3D model and experimental data are also given
