“…This causes an urgent need to create advanced energy materials and technologies for supporting the sustainable development of renewable energy systems [ 11 , 12 , 13 , 14 , 15 ]. Hydrogen energy, due to eco-friendliness and high efficiency, has a high priority among other renewable energy systems [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. The joining of forces in the fields of inorganic materials science and engineering for energy production has allowed the creation of such devices for hydrogen production as protonic ceramic electrolysis cells and devices for using hydrogen as a fuel for protonic ceramic fuel cells [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”
