Abstract

Water management is crucial for the performance, durability, and stability of Polymer Electrolyte Membrane Fuel Cells (PEMFCs). Due to its importance, various methods for visualizing PEMFC's internal water distribution have been adapted to study and manage water within the cells. However, these methods often require large facilities, leading to high costs and significant barriers to entry. This study addresses these challenges by using a commercial Radiation (X-ray) Generator (RG) for internal water distribution visualization and comparing the results with synchrotron X-ray data from the Pohang Accelerator Laboratory (PAL) 9D beamline. Despite the lower resolution and potential beam distortion challenges, the RG shows promise for PEMFC water distribution visualization, suggesting the need for further research to refine water attenuation coefficients and build-up factors for improved measurement accuracy.
