Abstract:To address the issue of flooding in polymer electrolyte fuel cells (PEFCs), it becomes imperative to devise an electrode structure capable of actively removing accumulated liquid water within the gas diffusion electrode (GDE). This study aimed to construct a wettability patterned electrode by applying a hydrophilic solution onto the cathode-side gas diffusion layer (GDL). Furthermore, the distribution of liquid water within the patterned electrode during PEFC operation was visualized using X-ray imaging and im… Show more
