Fuel cell with metal hydride hydrogen storage
Bruzl, David ; Libich, Jiří (referee) ; Novák, Vítězslav (advisor)
The bachelor thesis deals with hydrogen fuel cells and hydrogen storage. It describes the history of fuel cell development, the principle of their function and their individual types, with a focus on low-temperature fuel cells, especially the PEMFC type. Hydrogen storage methods are also described, with a focus on metal hydride storage. The design and assembly of the H-200 fuel cell system is described, its basic characteristics are measured and its differences from the manufacturer's characteristics are discussed. The discharge behavior of the HS-760 metal hydride storage system is also included. This behavior is measured by a program that was developed in the Labview environment. The thesis contains a description of this program. The program and the measured data are in the electronic appendices. One chapter of the thesis is also devoted to the operating modes of the whole system.

Model of Bulk Energy Accumulation
Radil, Lukáš ; Barath, Peter (referee) ; Gregor, Jan (advisor)
The purpose of this pursuit is to introduce the reader about the questions of the accumulation of the electric energy and to outline possibilities of its design and what instruments is possible to get it. The other purpose is to inscribe possibilities of today´s attachment of dispersive sources to the net from the sight of the ERU, eventually from the sight of the UCTE. This persuit describes the posibility of the accumulation of adequate dimensions from renewable resources, the modern trends in this area and the prediction of future progress. The two most proper types of the energy accumulation are chosen by the following process with regarding to the optimal resolution of the given questions. The general balance will be ana-lysed by the comparison of their basic parameters. The other point of this pursuit is to try to realize a small model of the accumulation through the hydrogen´s cycle, it comes to that we can develop the efficiency and influence by the help of the electrolyzer and the metalhydride reservoir is realized energy of accumulation . In the conclusion of this pursuit is the appreciation of the whole project with the view of partly economical and especially with the view of the prospective usage into the electric grid

Storage of hydrogen produced by electrolysis in a metal hydride
Hamřík, Lukáš ; Libich, Jiří (referee) ; Novák, Vítězslav (advisor)
In the theoretical part, this thesis focuses on the possibilities of producing hydrogen from renewable and non-renewable sources, mentioning their advantages and disadvantages. The work describes the properties and basic principles of several types of electrolysis technologies. Technological options for hydrogen storage in the gaseous, liquid and solid phases are listed, in particular with a focus on hydrogen storage in metal hydride storage sites. In practical part, the hydrogen system that was the subject of the measurement is described. Block diagrams and a description of the realisation of control and measurement system engagement are provided, and the method of reading and writing data using LabVIEW is described. The resulting measured temperature and pressure dependencies of the metal hydride storage, their comparison with theoretical knowledge, as well as the two possible modes in which the assembled hydrogen system can be operated are described below.
