摘要： The present disclosure relates to a method for preparing a carbon-supported platinum-transition metal alloy nanoparticle catalyst. More particularly, the present disclosure provides a method for preparing a carbon-supported platinum-transition metal alloy nanoparticle catalyst using a stabilizer, the method including the steps of: (a) mixing a platinum precursor, a transition metal precursor, carbon, stabilizer and a reducing agent solution, and carrying out washing and drying to obtain carbon-supported platinum-transition metal alloy nanoparticles; (b) mixing the carbon-supported platinum-transition metal alloy nanoparticles with an acetic acid solution, and carrying out washing and drying to obtain acetic acid-treated nanoparticles; and (c) heat treating the acetic acid-treated nanoparticles. Thus, it is possible to obtain a carbon-supported platinum-transition metal alloy nanoparticle catalyst through a more simple and eco-friendly process as compared to the related art, and to apply the catalyst to a high-performance and high-durability fuel cell catalyst.

摘要： Provided is an electrocatalyst for anion exchange membrane water electrolysis, including a carbonaceous material, and nickel electrodeposited on the carbonaceous material, wherein nickel is partially substituted with platinum and the substitution with platinum provides increased hydrogen evolution activity as compared to the same electrocatalyst before substitution with platinum. Also provided are a method for preparing the electrocatalyst and an anion exchange membrane water electrolyzer using the same. The nickel electrocatalyst coated with an ultralow loading amount of platinum for anion exchange membrane water electrolysis shows excellent hydrogen evolution activity and has a small thickness of catalyst, thereby providing high mass transfer and high catalyst availability. In addition, the electrocatalyst uses a particle-type electrode to facilitate emission of hydrogen bubbles generated during hydrogen evolution reaction and oxygen bubbles generated during oxygen evolution reaction, and requires low cost for preparation to provide high cost-efficiency.

摘要： Disclosed is an antioxidant for a polymer electrolyte membrane of a fuel cell including cerium hydrogen phosphate (CeHPO4). The presence of cerium hydrogen phosphate in the antioxidant enhances the dissolution stability of cerium and improves the ability to capture water, leading to an increase in proton conductivity. In addition, the cerium hydrogen phosphate has a crystal structure composed of smaller cerium particles. This crystal structure greatly improves the ability of the antioxidant to prevent oxidation of the electrolyte membrane. Also disclosed are an electrolyte membrane including the antioxidant, a fuel cell including the electrolyte membrane, a method for preparing the antioxidant, a method for producing the electrolyte membrane, and a method for fabricating the fuel cell.
