  1. 1. On direct hydrogen fuel cell vehicles modelling and demonstration

    University dissertation from Stockholm : KTH

    Author : Kristina Haraldsson; KTH.; [2005]
    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; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP 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

  2. 2. Development of a methanol reformer for fuel cell vehicles

    University dissertation from Stockholm : Kemiteknik

    Author : Bård Lindström; KTH.; [2003]
    Keywords : methanol; fuel cell vehicles; reforming; catalysis; partial oxidation; steam reforming; combined reforming;

    Abstract : Vehicles powered by fuel cells are from an environmentalaspect superior to the traditional automobile using internalcombustion of gasoline. Power systems which are based upon fuelcell technology require hydrogen for operation. The ideal fuelcell vehicle would operate on pure hydrogen stored on-board. READ MORE
