Study of sensoric properties of organic semiconductors
Saska, Pavel ; Šedina, Martin (referee) ; Salyk, Ota (advisor)
Compounds based on diketopyrrolopyrrole are organic pigments that behave as semi-conductors. Their analogues with pyridyl side group are due to their sensitivity to hydrogen potentially useful as hydrogen sensors. The aim of this work was to examine properties of sensors with an active layer of diketopyrollopyrolle derivatives. The sensors were tested on an apparatus built for this purpose at FCH VUT in Brno. More specifically, changes to conductivity of these sensors in the presence of hydrogen under various conditions were studied.

Hydrogen fuel for internal combustion engines
Polnický, Václav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Knowledge of all ower the world research, dealing with hydrogen combustion engines, were sumarized in this bachelor thesis. Ways of hydrogen production and its storing are mentioned too. This paper is focused especially to hydrogen-air mixture formation and its ignition solving. Some samples of hydrogen cars –booth of prototypes and serial products- were introduced too.

Fuel for internal combustion engines
Vrbický, Jiří ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
This thesis is concerned with basic features of fuels for internal consumption engines, especially their influence on thermal efficiency. It also introduces dividing of fuels and their compare in ecologic, economic and technologic side. It is concerned convectional fuels (gasoline, diesel oil) and alternative fuels (nature gas, bottled gas, hydrogen, biodiesel, biogas, methanol and ethanol).

Fuel cells in personal transport
Říha, Stanislav ; Blaťák, Ondřej (referee) ; Zháňal, Lubor (advisor)
This thesis is oriented to historical evolution of fuel cell, his total analysis, description of single disadvantage and advantage with which fuel cells battle. An other reason for urgency of using alternative fuel, brief description of car market and possible guess of fuel cell's future in personal transport are involved in an other part of this thesis. The end of the thesis deal with cars of fuel cells split in parts according to single car companies.

Omezené zásoby ropy a alternativní zdroje energie ? energetická závislost a její vliv na světovou ekonomiku
Mišoň, Petr ; Bič, Josef (advisor) ; Turečková, Andrea (referee)
Práce pojednává o postavení ropy ve světové ekonomice jako jedné z nejdůležitějších energetických surovin. Je zde podána hlubší charakteristika ohledně světových zásob ropy, světových trendů ve spotřebě ropy, investic do ropného průmyslu, ekologických dopadů vyvolaných spotřebou ropy, energetické závislosti světové ekonomiky na ropě a charakteristika využití ropy v dopravě. Další část práce je věnována využití a aplikaci alternativních zdrojů energie v dopravě a podrobnější charakteristice biopaliv a vodíku, jako alternativ ke konvenčním palivům.
