Modelling of Air Supply by Compressor for Fuel Cell
Tkach, Svitlana ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
The growing demand for freight transport and the long-term trend towards low-emission on-road trucks are driving a lot of attention towards fuel cell technology. Nowadays, computer simulations can be used to analyse complex fuel cell processes, which facilitates the time and cost of development. In this thesis, a computational model of a fuel cell system with a focus on air supply analysis is presented. An improvement in the performance characteristics of the air supply system, and therefore the fuel cell, can be achieved by using a compressor. Based on the initial design, an analysis of the influence of the compressor parameters at the design point on its power input is performed. An increase in compressor speed and isentropic efficiency at the design point led to a decrease in the required power input, while an increase in the pressure ratio at the design point led to an increase. As the result of the diploma thesis, an efficient tool for achieving optimal parameters of the fuel cell air supply system while minimizing the compressor input power is presented.

MEB modular platform for electric cars
Tkach, Svitlana ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor’s thesis focuses on the possibilities of the newly developed modular electric drive matrix MEB of the Volkswagen Group. The aim was to create a research study about technical parameters of the platform and the possibilities of its use for various categories of vehicles not only within the Volkswagen Group, but also the offer to competing manufacturers. In conclusion of the bachelor’s thesis is formulated the impact of technologies, offered by the modular electric drive matrix, on the development and production of electric vehicles and the related possibility of a reversal in the expansion of electric drive.
