[edit] Reference to specific scientist removed
I have removed the sentence: "Dr. Ronny Huang of Cornell University is the chief researcher of this cutting edge science and has written numerous publications." for a variety of reasons. Firstly, I can find no reference to Dr. Ronny Huang at Cornell. If you do a person search, you won't find him listed as faculty. Furthermore, if you explicitly check the departments of Materials Science and Engineering or Chemical Engineering, or Chemistry and Chemical Biology, you won't find him listed. In addition, there are literally hundreds of researchers working in the field of fuel cells, so one can hardly be singled out as "the chief researcher." Furthermore, if Dr. Huang really has published "numerous" papers in this field, I cannot find any of them on scientific search engines, such as web-of-science (registration required) or even google scholar. It seems like this entry is not legitimate and I am therefore removing it.
[edit] Details, details, details
How is this stuff made? Are relevant monomers known, e.g. CF2=CFSO3H and CF2=CF-CF2SO3H? Is Nafion processable - soluble, spinnable, extrudable, etc.? How is it coated onto electrodes etc? How acidic is it? --Smokefoot 04:46, 27 February 2006 (UTC) A precursor polymer is made by copolymerization of CF2=CF2 (TFE) and a perfluorovinyl ether monomer with an -SO2F functional group : CF2=CF-O-CF2CF(CF3)-O-CF2CF2-SO2F. This precursor is extrudable etc. and once fabricated to the final shape (film etc.) converted to the final polymer by treatment with hot NaOH solution followed by acid exchange to yield -SO3H functional groups. This can be converted to a "liquid composition" (possibly not a true solution) in a water / alcohol solvent.70.20.204.155 15:57, 2 September 2006 (UTC)W.Grot151.197.54.195 20:51, 25 February 2007 (UTC)
[edit] Additional information
I will add the importance of structure and more specific reactions very soon. --Trikes120 06:26, 28 February 2006 (UTC)
[edit] Featured article potential?
This article has come a very long way forward since the beginning of the year. I wouldn't be able myself to address the questions arising from a Featured Article Candidate critique, but I think this article would make a fine candidate for consideration.

I would be willing to help, particularly discussing the importance for mankind / environment (reduction of mercury pollution and energy consumption). I just finished the draft for a book "Fluorinated Ionomers" and sent it of to the publisher. W. Grot 151.197.54.195 20:48, 25 February 2007 (UTC)
