Supporting information Free Standing Graphene Oxide Paper: New Polymer Electrolyte for Polymer Electrolyte Fuel Cells

Graphite oxide was synthesized from natural flake graphite by the modified Hummers method. In brief, 200 mg of Graphite particles were immersed in Concentrated sulfuric acid (46 ml) and KMnO4 (6 g) was added slowly in small quantities in which temperature was maintained between the 0 and 5 c using an ice bath, after the complete oxidation of KMnO4, the mixture was heated to 37 c and kept at thi...

Mathematical Modeling of Transport Phenomena in Polymer Electrolyte and Direct Methanol Fuel Cells

This thesis deals with modeling of two types of fuel cells: the polymer electrolyte fuel cell (PEFC) and the direct methanol fuel cell (DMFC), for which we address four major issues: a) mass transport limitations; b) water management (PEFC); c) gas management (DMFC); d) thermal management. Four models have been derived and studied for the PEFC, focusing on the cathode. The first exploits the sl...

Catalyst supports for polymer electrolyte fuel cells.

A major challenge in obtaining long-term durability in fuel cells is to discover catalyst supports that do not corrode, or corrode much more slowly than the current carbon blacks used in today's polymer electrolyte membrane fuel cells. Such materials must be sufficiently stable at low pH (acidic conditions) and high potential, in contact with the polymer membrane and under exposure to hydrogen ...

Liquid methanol concentration sensors for direct methanol fuel cells

Liquid-fed direct methanol fuel cells (DMFCs) are one of the most promising candidates for portable power electronics and automotive pplications due to their potentially high-energy density, simple storage, and distribution of the fuel. The concentration of methanol in the fuel irculation loop of a DMFC system is an important operating parameter, because it determines the electrical performance...
