Abstract:The purposes of this research are designing the prototype of DMFC, consist of graphite and aluminium cell stacks and MEA with difference Nafion content. Cell stack has active area of 6.5 cm2, and single serpentine flow field. MEAs were fabricated using Nafion membrane 117 (DuPont), gas diffusion layer (GDL) carbon cloth, and commercial catalysts E-Tek, Pt/C for the cathode side and Pt-Ru/C for the anode. Catalysts loading on the anode are 3 and 4 mgPt-Ru/cm2 and on the cathode is 3 mg/cm2. Dry Nafion content… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
