Proc. ASME. FUELCELL2011, ASME 2011 9th International Conference on Fuel Cell Science, Engineering and Technology, 171-180, August 7–10, 2011
Paper No: FuelCell2011-54697
... In this work, it is shown that a novel tubular-shaped, passive Direct Methanol Fuel Cell (DMFC) can produce up to 2 times the instantaneous volumetric power density of a planar DMFC. First a numerical model was developed to determine the benefits of a tubular geometry and design characteristics...

... direct methanol fuel cell: methanol flow through anodic-serpentine channels; air flow through the cathodic-serpentine channels; dilute sulfuric acid flow through the flowing electrolyte (FE) channel located between two membrane-electrode assemblies (MEAs). The methanol flow rate is varied from 5 to 25 mL...

Proc. ASME. FUELCELL2005, 3rd International Conference on Fuel Cell Science, Engineering and Technology, 367-372, May 23–25, 2005
Paper No: FUELCELL2005-74010
... The flow-field design of Direct Methanol Fuel Cells (DMFCs) is an important subject about the DMFCs performance. Flow-fields play an important role on ability to transport fuel and drive out the products (H 2 O, CO 2 ). In general, most of fuel cells utilize the same structure of flow-field...
