摘要： Provided is a catalyst for oxygen reduction reaction comprising an alloy comprising at least one selected from Pt, Pd and Ir supported on a carbon carrier functionalized with poly(N-isopropylacrylamide) (PNIPAM). The catalyst for oxygen reduction reaction has electronic ensemble effects by virtue of the carbon carrier functionalized with poly(N-isopropylacrylamide) (PNIPAM), and thus shows improved oxygen reduction activity and durability as compared to conventional catalysts supported on carbon.

摘要： Provided are: a dry reforming catalyst, in which a noble metal (M) is doped in a nickel yttria stabilized zirconia complex (Ni/YSZ) and an alloy (M-Ni alloy) of the noble metal (M) and nickel is formed at Ni sites on a surface of the nickel yttria stabilized zircona (YSZ); a method for producing the dry reforming catalyst using the noble metal/glucose; and a method for performing dry reforming using the catalyst. The present invention can exhibit a significantly higher dry reforming activity as compared with Ni/YSZ catalysts. Furthermore, the present invention can have an improved long-term performance by suppressing or preventing the deterioration. Furthermore, the preparing method is useful in performing the alloying of noble metal with Ni at Ni sites on the Ni/YSZ surface and can simplify the preparing process, and thus is suitable in mass production.

摘要： Provided is a catalyst for an oxygen reduction reaction, including an alloy in which two metals are mixed, in which the corresponding alloy is an alloy of iridium (Ir); and silicon (Si), phosphorus (P), germanium (Ge), or arsenic (As). The corresponding catalyst for the oxygen reduction reaction may have excellent price competitiveness while exhibiting a catalytic activity which is equal to or similar to that of an existing Pt catalyst. Accordingly, when the catalyst is used, the amount of platinum catalyst having low price competitiveness may be reduced, so that a production unit cost of a system to which the corresponding catalyst is applied may be lowered.

摘要： 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.
