Fuel cell propulsion for unmanned aerial vehicles

U početnom dijelu ovog rada opisane su tehnologije gorivnih ćelija i način rada istih. Zatim pokazana je povijest rada gorivnih ćelija te njihov razvoj. U sljedećim poglavljima prikazana je podjela gorivnih ćelija, prednosti i nedostaci pojedinih vrsta gorivnih ćelija, te mogućnost njihove primjene. Zatim se je govorilo o proizvodnji vodika, što nam najviše govori o tome hoće li tehnologija gorivnih ćelija biti čista i u kojoj mjeri će zagađivati okoliš. Također, uz to prikazane su tehnologije skladištenja vodika, te tehnologije za prijevoz kopnom ili morem. U sljedećem poglavlju uspoređivane su gorivne ćelije i litij-ionske baterije kao izvori energije za bespilotne letjelice. U šestom poglavlju dani su primjeri u svijetu bespilotnih letjelica pogonjenih na gorivne ćelije. U završnom poglavlju pokazan je primjer bespilotne letjelice pogonjene vodikovim ćelijama, te su prikazana njezine karakteristike. Proračunat je spremnik potreban za pogon letjelice i opisani osnovni sustavi potrebni za pokretanje navedene letjelice.In the beginning of this master thesis fuel cell technology and work principle is explained. Following that, fuel cell history and development is shown. Following chapters show fuel cell catagorisation, advantages and disadvantages of specific fuel cells and possibilities of its applications. Then there was talk about hydrogen production, which tells us the most about how clean will fuel cell technology will be and in what way will it impact the environment. Hydrogen storage technologies are shown as well as for its transportation whether by land or sea. Next chapter compares fuel cells and lithium-ion batteries used as source energy for unmanned aerial vehicle . In sixth chapter, examples of unmanned aerial vehicles in the world powered by fuel cells are given. Final chapter shows an example of unmanned aerial vehicle powered by fuel cells and its characteristics. Hydrogen tank, need for vehicle propulsion, is dimensioned and basic systems needed for starting the said vehicle are described
