In this feasibility study, high-resolution neutron tomography is used to investigate the water distribution in polymer electrolyte membrane fuel cells (PEMFCs). Two PEMFCs were built up with two different gas diffusion layers (GDLs) namely Sigracet®

An important step in the analysis of liquid water distributions in high resolution tomographies of PEMFCs is the segmentation of water and cell materials. This is conducted via subtraction of the dry from the operated state of the cells. The morpholo

The water management in proton exchange membrane fuel cells (PEMFC) is strongly influenced by the design of the gas diffusion layers (GDL). Limiting current measurements in small-scale cells operating at high stoichiometries are useful to determine t

We present a study on a new type of flow field channel design for polymer electrolyte membrane fuel cells (PEMFCs). Small barriers have been implemented into the flow field channels that force the gas flow to move through the gas diffusion layers in
