Membrane Electrode Assembly Degradation Modeling of Proton Exchange Membrane Fuel Cells: A Review

Proton exchange membrane fuel cells (PEMFCs) have been recognized as a promising power generation source for wide range of automotive, stationary, and portable electronic applications. However, the durability PEMFCs remains one key barriers to their commercialization. The electrode assembly (MEA) central part PEMFC, which consists proton with catalyst layer (CL) gas diffusion (GDL) on each side, is subject failure degradation in long-running cycling load conditions. real-time monitoring evolution process through experimental techniques challenging. Therefore, different numerical modeling approaches were proposed literature assist understanding mechanisms PEMFCs. To provide progress addressed field, this paper briefly discusses occurring MEA. In particular, we present detailed review MEA research work, special attention paid physical-based models (mechanistic models). Following most recent relevant literature, results showed that combination microstructure component macro-scale comprehensive PEMFC provides better when compared single-scale models. sense, it concluded order develop an accurate efficient predictive model, scales ranging from nano- macro-sized should be considered, coupling multiscale advanced. Finally, summarizes components. It highlighted GDL chemical describe damage accumulation are relatively limited. useful reference developments
