Electrolyte polymer for fuel cell, method for producing same, electrolyte membrane, and membrane electrode assembly |
| abstract |
Disclosed are an electrolyte polymer for fuel cells having excellent durability, an electrolyte membrane and a membrane electrode assembly. Specifically disclosed is an electrolyte polymer for fuel cells which is composed of a perfluorocarbon polymer having an ion exchange group (which may contain an ether oxygen atom) and characterized in that the value obtained by dividing the absorbance area (SCH) mainly ascribed to C-H bonds, which is measured within the range from 3100 cm-1 to 2800 cm-1 by infrared spectroscopy, by the peak absorbance area (SCF) mainly ascribed to C-F bonds, which is measured within the range from 2700 cm-1 to 2000 cm-1, is less than 0.005. |
