dc.description.abstract Various clean and renewable energy devices/sources such as solar cells, wind power, geothermal, and tidal power have been suggested to solve global warming and energy depletion. Among suggested energy sources, hydrogen energy is considered as a promising alternative to replace conventional combustion systems due to its feasibility and sustainability. Moreover, the hydrogen can act as a clean and efficient energy source as well as an energy carrier which can save the energy from renewable energy sources. The most hydrogen devices work with several electrochemical reactions including oxygen reduction reaction (ORR), oxygen evolution reaction, (OER), hydrogen oxidation reaction (HOR), and hydrogen evolution reaction (HER). The development of effective electrochemical catalysts is required because those electrochemical reactions have a slow reaction rate. Therefore, I focus on the development of hydrogen-related catalysts and electrodes having outstanding and robust electrical, electrochemical and thermal properties to properly demonstrate various hydrogen-related energy devices, in this study. Moreover, I introduce several researching achievements with fundamental knowledge including operating principles and theoretical backgrounds as presented as follows. 1. Materials for Energy conversion device (cathode of the solid oxide fuel cell) • Influence of Ca-doping in layered perovskite PrBaCo2O5+δ on the phase transition and cathodic performance of a solid oxide fuel cell • Investigation of the Fe doping effect on the B-site of the layered perovskite PrBa0.8Ca0.2Co2O5+δ for a promising cathode material of the intermediate temperature solid oxide fuel cells • Ca and Ni-doped Pr0.5Ba0.5FeO3-δ as a highly active and robust cathode for high-temperature solid oxide fuel cell 2. A catalyst for energy storage devices: Nano-perovskite oxide prepared via inverse microemulsion mediated synthesis for the catalyst of lithium-air batteries -
