3D experimental visualization of water flooding in proton exchange membrane fuel cells

In Proton Exchange Membrane Fuel Cell (PEMFC) heat and water are generated as a side production. The accumulated water leads to a decrease in PEMFCs' efficiency. Hence, water has to be removed in order to prevent flooding inside the cell. In this study, by using experimental transparent Gas Diffusion Layer (GDL) water transport in PEMFC is visualized, and the capillary fingering mechanisms are studied. The effect of adding Micro Porous Layer...
