Abstract
The present invention aims at providing an optimal constitution and production method for an OH-type anion-exchange hydrocarbon-based elastomer used when manufacturing a catalyst electrode layer of a solid polymer type fuel cell, in view of a balance of stability, durability and flexibility. Also, the present invention aims to provide an ion-conductivity imparting agent comprising the OH-type anion-exchange hydrocarbon-based elastomer, wherein the elastomer is uniformly dissolved or dispersed and has appropriate viscosity even with a high concentration. The anion-exchange hydrocarbon-based elastomer of the present invention has an iodine value of 3 to 25, contains an anion-exchange group having OH, COand/or HCOas a counterion in its molecule and is poorly-soluble in water. The hydrocarbon-based elastomer can preferably be used as an ion-conductivity imparting agent for forming a catalyst electrode layer by mixing an organic solvent.
