| 520 | _ | _ | |a Numerous areas of application, such as aviation or heavy goods transport, have no medium-term alternative to the middle distillates currently in use, namely diesel and kerosene. For both economic and environmental reasons, optimizing the efficiency of the systems in use is therefore a key objective. In achieving this objective, fuel cells are a promising option. Due to the lacking hydrogen infrastructure, fuel cells are equipped with an on-board supply system. The hightemperature polymer electrolyte fuel cell (HT-PEFC) is particularly suitable for such applications due to its high CO tolerance, simple water and heat management, and moderate material loads. The aim of the present project is to develop a stack design for a 5-kW HTPEFC system. First, the state of the art of potential materials and process designs will be discussed for each component. Then, using this as a basis, three potential stack designs with typical attributes will be developed and assessed in terms of practicality with the aid of a specially derived evaluation method. Two stack designs classified as promising will be discussed in detail, constructed and then characterized using short stack tests. Comparing the stack designs reveals that both designs are fundamentally suitable for application in a HT-PEFC system with on-board supply. However, some of the performance data differ significantly for the two stack designs. The preferred stack design for application in a HT-PEFC system is characterized by robust operating behaviour and reproducible high-level performance data. Moreover, in compact constructions (120 W/l at 60 W/kg), the stack design allows flexible cooling with thermal oil or air, which can be adapted to suit specific applications. Furthermore, a defined temperature gradient can be set during operation, allowing the CO tolerance to be increased by up to 10 mV. The short stack design developed within the scope of the present work therefore represents an ideal basis for developing a 5-kW HT-PEFC system. Topics for further research activities include improving the performance by reducing weight and/or volume, as well as optimizing the heat management. The results achieved within the framework of this work clearly show that HTPEFC stacks have the potential to play a decisive role in increasing efficiency in the future, particularly when combined with an on-board supply system. |
