Abstract
Provided are a proton conductor and a single ion conductor both having higher conductivity and a wider operating temperature range, and a method of producing the same. A polymer including a structure portion represented by Chemical Formula 49, and an organic compound represented by Chemical Formula 50 or an organic compound represented by Chemical Formula 51 are included. Each of R1, R2, R3 and R4 is a component including carbon, and each of X1, X2, X3, X4 and X5 is a proton dissociative group. Further, n is n>1, and p is p>0, and the number of carbons in R4 is within a range from 1 to 4. Proton transfer can be promoted by an ether bond or the proton dissociative group of the organic compound, and the number of protons can be increased by the proton dissociative group of the organic compound, thereby the proton transfer can be smoothed.
