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.

Application of the risk index matrix principles to electric power distribution system elements
Bruzl, David ; Hála, Vojtěch (referee) ; Ptáček, Michal (advisor)
The master thesis deals with the evaluation of the use of the risk index matrix (RIM) principle for distribution system elements. It evaluates the current use of RIM in EG.D, a.s., examines the individual RIM inputs and also reveals the bottlenecks. An updated method of assigning elements to the RIM is proposed that addresses the problems described and is also generally applicable to other distribution system elements at medium and low voltage levels. At the same time, a sensitivity analysis is performed to investigate the influence of different factors on the RIM and to verify the stability of the categorization of the resulting RIM. The thesis also serves as a methodology for assigning elements to the RIM and includes recommendations for the distribution system operator (DSO).
