Design and manufacture of a high-temperature PEMFC and its cooling system to power a lightweight UAV for a high altitude mission 2016 Access copy available to the general public Unrestricted In the present study, the optimal design of a high-temperature proton exchange membrane fuel cell (HT-PEMFC) that will be used to power an unmanned aerial vehicle (UAV) in a high altitude mission is performed. The use of PEMFCs for service ceiling above 10 km implies overcoming a number of problems caused by the harsh environmental conditions. Among them, new strategies to manage the heat generated by electrochemical reactions are needed. The maximum power required by the UAV was determined solving the aerodynamic problem, and the design of the lightweight HT-PEMFC, including its cooling system, was optimized. To perform the numerical solution of the heat transfer problem, a computational code was implemented using the EES software. The decisions adopted resulted in a 40-cells stack with an electric power above 1 kW and a weight around 3.65 kg. Besides, it is demonstrated that, for the configuration considered in the study, a passive cooling system without any additional fan system can be used to maintain the stack temperature in 160 °C. info:eu-repo/grantAgreement/ES/DGA/T03 info:eu-repo/grantAgreement/ES/MINECO/ENE2012-38642-C02-01/CON info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.582 2016 ELECTROCHEMISTRY 7 / 27 = 0.259 2016 Q2 T1 ENERGY & FUELS 28 / 89 = 0.315 2016 Q2 T1 CHEMISTRY, PHYSICAL 45 / 144 = 0.312 2016 Q2 T1 1.145 2016 Condensed Matter Physics 2016 Q1 Renewable Energy, Sustainability and the Environment 2016 Q1 Fuel Technology 2016 Q1 Energy Engineering and Power Technology 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Barroso, J.
