An electrolyte membrane for use in a fuel cell can contain sulfonated polyphenylether sulfones. The membrane can contain a first sulfonated polyphenylether sulfone and a second sulfonated polyphenylether sulfone, wherein the first sulfonated polyphenylether and the second sulfonated polyphenylether sulfone have equivalent weights greater than about 560, and the first sulfonated polyphenylether and the second sulfonated polyphenylether sulfone also have different equivalent weights. Also, a membrane for use in a fuel cell can contain a sulfonated polyphenylether sulfone and an unsulfonated polyphenylether sulfone. Methods for manufacturing a membrane electrode assemblies for use in fuel cells can include roughening a membrane surface. Electrodes and methods for fabricating such electrodes for use in a chemical fuel cell can include sintering an electrode. Such membranes and electrodes can be assembled into chemical fuel cells.
A membrane for use in a fuel cell, wherein the membrane is comprised of a blend comprising a first sulfonated polyphenylether sulfone and a second sulfonated polyphenylether sulfone, said first sulfonated polyphenylether sulfone and said second sulfonated polyphenylether sulfone having equivalent weights greater than about 560, and said first sulfonated polyphenylether and said second sulfonated polyphenylether sulfone having different equivalent weights.
