Abstract: The present disclosure relates to a catalyst for a fuel cell, a fuel cell including the same and a method for preparing the catalyst for a fuel cell. More specifically, the catalyst for a fuel cell according to the present disclosure can exhibit superior catalytic activity as compared to the existing catalyst even when the catalyst metal is used at a very low content because some metal of the metal nanoparticles distributed on a carbon support is replaced with catalyst metal single atoms.

Abstract: The present disclosure relates to a polybenzimidazole-based electrolyte membrane for alkaline water electrolysis, which includes a polybenzimidazole-based polymer, wherein the polybenzimidazole-based polymer is a biaxially oriented film. The polybenzimidazole-based electrolyte membrane for alkaline water electrolysis can reduce the concentration of an alkaline solution by improving the crystallinity of a polybenzimidazole-based polymer to increase the resistance against base, significantly improving the long-term stability of alkaline water electrolysis using a polybenzimidazole-based electrolyte membrane through the improved resistance against base, and by increasing the operation temperature to enhance the catalyst activity.

Abstract: The present disclosure relates to a fuel cell catalyst and a manufacturing method thereof. The fuel cell catalyst of the present disclosure can be used to manufacture a membrane electrode assembly having a catalyst layer of high density and high dispersion by solving the problem of aggregation of catalyst particles occurring during the formation of the catalyst layer, by using a catalyst including a polydopamine-coated support.
In addition, the method for manufacturing a fuel cell catalyst of the present disclosure does not require a solvent because the catalyst including the polydopamine-coated support and the halide in solid phase are simply heat-treated by solid-to-solid dry synthesis and allows manufacturing of a fuel cell catalyst in short time because a washing process using a solvent and an extraction process for sampling are unnecessary after the synthesis.-

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: Disclosed is a method for preparing a carbon-supported platinum-transition metal alloy nanoparticle catalyst using a stabilizer. According to the method, the transition metal on the nanoparticle surface and the stabilizer are simultaneously removed by treatment with acetic acid. Therefore, the method enables the preparation of a carbon-supported platinum-transition metal alloy nanoparticle catalyst in a simple and environmentally friendly manner compared to conventional methods. The carbon-supported platinum-transition metal alloy nanoparticle catalyst can be applied as a high-performance, highly durable fuel cell catalyst.

Abstract: Disclosed is a method for preparing a carbon-supported metal oxide and/or alloy nanoparticle catalyst. According to the method, a carbon-supported metal oxide and/or alloy nanoparticle catalyst is prepared by depositing metal oxide and/or alloy nanoparticles on a water-soluble support and dissolving the metal oxide and/or alloy nanoparticles deposited on the water-soluble support in an anhydrous polar solvent containing carbon dispersed therein to support the metal oxide and/or alloy nanoparticles on the carbon. The anhydrous polar solvent has much lower solubility for the water-soluble support than water and is used to dissolve the water-soluble support. The use of the anhydrous polar solvent instead of water can prevent the water-soluble support present at a low concentration in the solution from impeding the support of the nanoparticles on the carbon, thus providing a solution to the problems of environmental pollution, high cost, and complexity encountered in conventional chemical and physical synthetic methods.

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.
