| Annotation: | The development of activities in the field of hydrogen technologies was also supported by the EuropeanCommission in the strategic document "Hydrogen Strategy for a Climate Neutral Europe". Today, Slovakia hassuggested own national hydrogen strategy. Already in 2015, the National Hydrogen Association has founded tosupport research, implementation and use of hydrogen technologies. The Hydrogen Technology Center is beingestablished in Košice with the main "Power-to-Gas" concept using renewable power energy sources with nonegative impact on human life and without dependence on fossil fuels. A significant source of hydrogen is waterand the electrolysis of water is the most promising technology for hydrogen production. However, before it can berecognized as an economically significant resource for large scale application with an exceptional energy potential,the simple, efficient, and secure methods of hydrogen retrieval have to be developed. For the time being, the mostefficient electrocatalysts in terms of overpotential for hydrogen evolution reaction (HER) are noble metals.Unfortunately the high cost and scarcity of noble metals motivate the scientists to find the rival low-costalternatives. Intrinsic structures of TMP meet the criteria of outstanding electrocatalysts that could further improve their HER performance in membrane electrode assembly. Excellent dispersity of electrocatalysts allows full use ofactive sites on catalysts to participate in electrode reaction to improve the electrocatalytic efficiency. Therefore, themain challenge in this project is to reduce the production cost of HER and at the same time to maintain the highefficiency of polymer electrode water electrolysis. Substantial aim of the project will be devoted to improve the PEM water electrolysis components mainly electrode materials based on modified carbon fibers electrocatalysts result in the technology which should be more approached to commercial markets. |

| Annotation: | Hydrogen produced from renewable energy sources is considered to be a fuel of the future that has the potentialto reduce the energy dependence of developed countries on oil imports and to improve the quality of human life.Hydrogen produced from electrolysis of water could be a sustainable source of energy. However the simple,efficient, and secure methods of hydrogen retrieval must be developed before it can be recognized as aneconomically significant resource with an exceptional energy potential. The project is devoted to the preparationof new catalysts for the effective hydrogen evolution from water. The porous carbon fibers modified with metallicnanoparticles and metallic phosphide nanoparticles will be prepared by needle-less elektrospinning technologyfrom the free surface of polymers, to catalyze the production of hydrogen at low overpotential.The outcomes ofthe project will be design of a compact electrode composed of modified carbon fibers that would effectivelycatalyse hydrogen evolution. |
