Abstract: Provided are a hydroxyl group-containing sulfonated polyethersulfone copolymer, a method for preparing the same, a polymer electrolyte membrane for fuel cell, and a membrane electrode assembly including the same. More particularly, provided are a hydroxyl group-containing sulfonated polyethersulfone electrolyte membrane and a membrane electrode assembly including the same, which are applied to a fuel cell to provide significantly higher ion conductivity as compared to the sulfonated polymer electrolyte membranes according to the related art. The hydroxyl group-containing sulfonated polyethersulfone copolymer electrolyte membrane shows significantly higher ion conductivity under various temperature and humidity conditions as compared to the sulfonated polymer electrolyte membranes according to the related art. Therefore, it is expected that the hydroxyl group-containing sulfonated polyethersulfone copolymer substitutes for expensive fluoropolymer electrolyte membranes such as Nafion.

Abstract: The present disclosure relates to a fluorine-doped tin oxide support, a platinum catalyst for a fuel cell comprising the same, and a method for producing the same. The present disclosure has a high electrical conductivity and electrochemical durability by doping fluorine to the tin oxide-based support through an electrospinning process. Thus, while resolving a degradation issue of the carbon support in the conventional commercially available platinum/carbon (Pt/C) catalyst, the present disclosure is designed to minimize an electrochemical elution of dopant or tin, which is a limitation of the tin oxide support itself and has excellent performance as a catalyst for a fuel cell.

Abstract: 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.
