Mitigating phosphoric acid migration in high temperature polymer electrolyte membrane fuel cells with hydrophobic polysilsesquioxane-based binders

Abstract

Cross-linkable organosilsesquioxanes were synthesized for application as catalyst binder in high temperature polymer electrolyte membrane fuel cells (HT-PEMFCs). Four different organic functional groups examined including methyl, phenyl, fluoroalkyl, and fluorophenyl...
