  1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jonathan Envall; [2023]
    Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Sammanfattning : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.
