摘要：
A novel electrolyte composition is provided for obtaining a solid electrolyte membrane capable of exhibiting a large ion exchange capacity, high proton conductivity and a low methanol permeation coefficient. This electrolyte composition contains a sulfonic acid group-containing polyimide and having a specific structure. Such a polyimide can be obtained, for example, by reacting 1,4,5,8-naphthalenetetracarboxylic dianhydride with a diamine compound.
