Polymer, polymer electrolyte membrane for polymer electrolyte fuel cell, and membrane/electrode assembly |
| abstract |
Disclosed is a solid polymer electrolyte membrane for solid polymer fuel cells having low electrical resistance and high heat resistance, which is durable against repeated swelling and shrinking. Also disclosed is a membrane electrode assembly having high power generation performance and excellent durability. Specifically, a polymer having the unit (U1) and the unit (U2) described below is used for a solid polymer electrolyte membrane (15). [chemical formula 1] (U1) (U2) In the above formulae, Q1, Q2 and Q3 respectively represent a perfluoroalkylene group or the like; Rf1 and Rf2 respectively represent a perfluoroalkyl group; X1 and X2 respectively represent an oxygen atom or the like; a and b respectively represent 0 or the like; Y1 and Y2 respectively represent a fluorine atom or the like; and s and t respectively represent a number of 0-1. |
