05 - PropulsionASSESSMENT OF A SERIAL COOLING CONCEPT FOR HTPEM FUEL CELL SYSTEMS FOR AVIATION APPLICATIONSA. Link¹, J. Ludowicy¹, M. Staggat¹; ¹German Aerospace Center (DLR), Germany A serial cooling concept for HTPEMFCs is proposed to reduce system weight for aviation applications by trading liquid coolant mass against fuel cell efficiency and mass. The presented studies across different system parameters of the fuel cell and thermal management system indicate that the proposed concept offers significant weight savings with limited drawbacks in system efficiency. |
