Abstract: A polybenzimidazole based polymer in which substituted or non-substituted benzyl groups are introduced to the two nitrogen atoms of benzimidazole ring. The benzimidazole ring is not decomposed by the attack of hydroxide ions but shows excellent alkali resistance, and thus maintains high ion conductivity. The polybenzimidazole based polymers are particularly useful for not only solid alkali exchange membrane fuel cells (SAEMFC) but also various industrial fields in which polybenzimidazole based polymers are used.
