  3. 3. Conceptual design and investigation of hydrogen-fueled regional freighter aircraft

    Author : Kolja Seeckt; Arthur Rizzi; Petter Krus; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Abstract : This thesis presents the conceptual design and comparison of five versions of regional freighter aircraft based on the ATR 72. The versions comprise four baseline designs differing in their propulsion systems (jet/turboprop) and the fuel they use (kerosene/hydrogen). READ MORE

  4. 4. On direct hydrogen fuel cell vehicles : modelling and demonstration

    Author : Kristina Haraldsson; Per Alvfors; Dougal J. Nelson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; direct hydrogen; Proton Exchange Membrane; PEM; fuel cell; fuel cell vehicle; fuel cell hybrid vehicles; on-board hydrogen storage; Kemiteknik; Chemical engineering; Kemiteknik;

    Abstract : In this thesis, direct hydrogen Proton Exchange Membrane (PEM) fuel cell systems in vehicles are investigated through modelling, field tests and public acceptance surveys. A computer model of a 50 kW PEM fuel cell system was developed. The fuel cell system efficiency is approximately 50% between 10 and 45% of the rated power. READ MORE
