PURPOSE: To provide a proton-conductive polymer solid electrolyte made of a specific polyether netted by a hardener, that has a high ion conductivity at room temperature and has good mechanical properties, by introducing an acid into the netted polyether. CONSTITUTION: A proton-conductive polymer solid electrode, comprising a polyether which is netted by a hardener containing two epoxy functional groups and which contains two first amine terminal functional groups, has an acid introduced into the netted polyether. The acid is selected from among inorganic acid, organic acid and polyacid that include -COOH functional group, organic acid and polyacid that include -SO3 H functional group, and their mixture. If the amount of acid in the electrolyte is too small, conductivity is insufficient. If the solubility of the acid in the polymer is limited, the weight ratio of the acid is 5-50%. The proportion of the acid becomes too much, and either the product becomes unstable or solubilization becomes very difficult. |
