Abstract: Provided are a high-crystallinity, porous, and hydrophilic catalyst for a fuel cell, a manufacturing method thereof, and a fuel cell using the same. The method of manufacturing a fuel cell provides a new carbon support composition having the following features: supporting of metal compounds by electron beam reduction of metal precursors, improvement of mesoporosity and dispersion of crystalline carbon obtained by metal vaporization by sequential low-temperature heat treatment, and improved performance stability in a low-humidity atmosphere.

Abstract: An embodiment of the present disclosure relates to an apparatus for synthesizing nanoparticles by irradiating, with an electron beam, a nanoparticle aqueous solution in a reaction vessel provided inside a shielding chamber, and more particularly, to an apparatus for synthesizing nanoparticles, which is capable of preventing radiation generated in a shielding chamber from leaking out, and facilitating maintenance and repair.

Abstract: The present disclosure relates to a fuel cell catalyst and a manufacturing method thereof. The fuel cell catalyst 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 the fuel cell catalyst does not require a solvent because the catalyst including the polydopamine-coated support, wherein from 0.1 to 1% of the hydroxy groups contained in catechol groups of the polydopamine are replaced by halide atoms, in solid phase are simply heat-treated by solid-to-solid dry synthesis which allows manufacturing of a fuel cell catalyst in a short time by eliminating the need for a washing process using a solvent and an extraction process for sampling after the synthesis.
