Technologies for storing electrical energy in electric vehicles
Zdražil, Marek ; Walek, Agata (referee) ; Langerová, Petra (advisor)
Tato bakalářská práce je zaměřena na technologie pro ukládání elektrické energie, s důrazem na jejich použití v elektrických vozidlech. První kapitola se zabývá historickým vývojem technologií pro ukládání elektrické energie a jejich použitím v prvních elektrických vozidlech. Dále popisuje elektrická vozidla, která byla sporadicky vyráběna v průběhu dvacátého století, až po devadesátá léta, kdy tato technologie opět nabyla na atraktivitě. V další části nalezneme rozdělení současných elektromobilů a zástupce těchto kategorií mezi automobily vyráběnými v současnosti. Třetí část se věnuje technologiím používaným v současnosti, či nedávné minulosti. Následně je uveden přehled technologií, které by mohly do budoucna nahradit současné systémy, nebo dokonce konvenční spalovací motory.

Low temperature Fuel Cells
Kazda, Tomáš ; Novák, Vítězslav (referee) ; Barath, Peter (advisor)
The Bachelor’s thesis is aimed at the low-temperature fuel cells and their usage in cars and mobile applications. In the theory part of this project is described the evolution of the fuel cells in last years and historically as well. Further there are described their functions and particular kinds of the fuel cells with aim at low-temperature cells. In the practical part of this thesis we were making different kinds of carbon mixtures. We have been doing measurements of mixtures on rotate disk electrode and in the experimental fuel cell. At the end of the work are experimentally evaluated different types of carbon materials with different contents of platinum depositing. The results are evaluated using electro analytical methods, using this evaluation to optimize the composition of the material used as electrode material in fuel cells.

Hydrogen for Power
Kocman, Lukáš ; Pospíšil, Jiří (referee) ; Skála, Zdeněk (advisor)
The increasing use of hydrogen in modern energy, has become the motive for writing this work. The work is focused on hydrogen energy and its aim was to compile an overview of hydrogen production technologies, the use of hydrogen technologies in current energetics and the use of hydrogen to energy accumulation. In addition to describing current hydrogen technologies, this work also includes examples of hydrogen devices and projects that we may encounter today. An overview of the above-mentioned technologies has shown that, despite some of its shortcomings, hydrogen has a significant application in current energetics, that is expected to increase in the coming years.

Methanol as an alternative fuel
Balcárek, Ondřej ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This Bachelor thesis is a topic review of problematics of alternative fuel solutions, in particular of methanol and it's production. The aim was to describe properties and possibilities of use of methanol, not only as fuel, but also as a raw material in chemical industry. The information was obtained mainly from English-written sources. Finally, in conclusion part, use and potential of methanol in period of transition to renewable sources is being reviewed.

"Power-to-Gas" Energy Storage Technology
Gálíček, Radomír ; Špiláček, Michal (referee) ; Poláčik, Ján (advisor)
Climate change is becoming a severe global issue which demands innovative technical solutions. If, in the context of reduction of gaseous carbon emissions, the share of renewable energy resources continued to rise, the need for energy storage would emerge. That could mean a shift towards hydrogen focused technologies. This bachelor’s thesis focuses on Power to gas processes and summarizes means of hydrogen production, storage and transportation. All the mentioned aspects are reviewed from technological and economical point of view. Conventional methods of hydrogen production from fossil fuels are the most common, but usage of electrolysis or biological methods may prove as competitive options in near future. Furthermore, the usage of fuel cells in the field of small-scale cogeneration units is recently going through a phase of dynamic development. The practical part of this thesis focuses on designing a seasonal Power to gas unit for a semi-detached house which is powered exclusively by renewable resources. From numerous variants the best one was chosen and compared to a conventional energy storage using lithium batteries. It is shown that even thou the electrochemical cells are more flexible variant they couldn’t match Power to gas technology in the term of seasonal energy storage.
