Simulation of steady-state and dynamic behavior of low-temperature fuel cell
Smugala, Ondrej ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This bachelor´s thesis is concerned with mathematic modelling of low temperature proton exchange membrane fuel cell (PEMFC). First part of the thesis is focused on explaining the principle of production of electricity by this type of source. The main advantages and disadvantages of this technology are presented there. A division of fuel cells according to the stack temperature and the kind of used electrolyte is also made in this part. Typical technical information is mentioned for every type of fuel cell. The rest of thesis is concerned with the PEMFC. Firstly there is a description of construction of fuel cell and a presentation of applications in the industry. The second part of work includes a mathematical description of steady and dynamic behavior of fuel cell which is based on relations among fundamental parameters and quantities. The other part contains all results of simulation which was made on a model created in Matlab Simulink. Comparison of the results of real measurement with the results of simulation which was performed on a modified model is provided in the last part of thesis.

Hypoxia in aviation
Doležel, Jan ; Šplíchal, Miroslav (referee) ; Hammer, Jaromír (advisor)
This bachelor thesis focuses on hypoxia in general and commercial civil aviation. The goal of the thesis is to create a general overview of hypoxia in aviation and the dangers connected to it. The thesis includes chapters describing the physiological principles of the human body, the physical laws associated with hypoxia, and the on-board oxygen and pressurization of aircraft. At the end of the thesis the author made an analysis of two aviation accidents caused by hypoxia.
