摘要: An aqueous coating composition is provided comprising carbon particles, one or more highly fluorinated polymers and amine oxide surfactants, typically an surfactant according to formula (I) where n 9 19. The advantageously used in a method of making gas diffusion layer for electrochemical cell the steps of: a) electrically conductive porous substrate with composition, b) heating temperature sufficient decompose surfactants. In another aspect, which free surfactant.
