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.

Abstract translation: 将取代或未取代的苄基引入苯并咪唑环的两个氮原子的聚苯并咪唑基聚合物。 苯并咪唑环不被氢氧根离子的侵蚀分解，但耐碱性优异，因此保持高的离子传导性。 基于聚苯并咪唑的聚合物不仅可用于固体碱交换膜燃料电池（SAEMFC），还可用于其中使用聚苯并咪唑的聚合物的各种工业领域。

Abstract: Disclosed is a homogeneous catalyst having a single phase of Perovskite oxide, wherein at least one doping element is substituted at site A, site B or sites A and B in ABO3 Perovskite type oxide so that the wettability with a liquid molten carbonate electrolyte may be decreased. The catalyst may have high catalytic activity, inhibit catalyst poisoning caused by creepage and evaporation of a liquid molten carbonate electrolyte, maintain high reaction activity for a long time, provide high methane conversion, and allow production of synthetic gas having a high proportion of hydrogen.
