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 ...
متن کاملSolid polymer electrolyte membranes for fuel cell applications—a review
Fuel cells represent a clean alternative to current technologies for utilizing hydrocarbon fuel resources. Polymer electrolyte membrane fuel cells (PEMFCs) have acquired due importance as they are best suited for applications where a quick start up is required such as in automobiles. The prime requirements of fuel cell membranes are high proton conductivity, low methanol/water permeability, goo...

Polymer electrolyte fuel cells (PEFCs) have attracted much interest due to the need for an efficient, non-polluting power source with high energy density for vehicles in urban environments, as well as portable electronics [...].
متن کاملModeling transport in polymer-electrolyte fuel cells.
In this review, we have examined the different models for polymer-electrolyte fuel cells operating with hydrogen. The major focus has been on transport of the various species within the fuel cell. The different regions of the fuel cell were examined, and their modeling methodologies and equations were elucidated. In particular, the 1-D fuel-cell sandwich was discussed thoroughly because it is t...
متن کاملSupporting 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...
