The influence of argon, air and hydrogen gas on thermal conductivity of gas diffusion layers and temperature gradients in PEMFCs
Bock, Robert; Hamre, Bjørnar; Onsrud, Morten Andreas; Karoliussen, Håvard; Seland, Frode; Burheim, Odne Stokke (Journal article; Peer reviewed, 2019)Gas diffusion layers (GDL) in fuel cells have to satisfy a range of conflicting demands. They must deliver good mass transport, but also good electrical and thermal transport. The thermal conductivity of two GDLs was ... -
Thermal Conductivity in PEMFC PTLs with Different Gas Content and Corresponding simple PEMFC Internal Temperature Profiles
Hamre, Bjørnar (Master thesis, 2017)More than 50 % of the PEMFC (Polymer Electrolyte Membrane Fuel Cell) energy is released as heat. The aim for this thesis was to contribute to the understanding of the management of that heat. The heat management in the ...
