Improvement of Oxygen Diffusion in Polymer Electrolyte Membrane Fuel Cells Using Superimposed Acoustic Pressure Waves

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Polymer electrolyte membrane fuel cells (PEMFCs) suffer from performance degradation under high‐load conditions owing to mass transport limitations caused by flooding. To address this problem, we investigated the effect of an acoustic pressure wave (AW) on oxygen transport and water management in a single‐channel PEMFC using a three‐dimensional ...
