To achieve high temperature operation of proton exchange membrane fuel cells, preferably under ambient pressure, phosphoric acid doped polybenzimidazole (PBI) membrane represents an effective approach, which has motivated extensive research activities. Significant progress has been achieved in both materials and the technology in recent years. The talk will start with a general introduction to the Nordic strategies and activities in the field of renewable and hydrogen energies, followed by report of recent R&D efforts on high temperature PEMFC, primarily based on the research made in Denmark. New insights on e.g. the proton conductivity will then be presented. The long-term durability has been a critical concern and will be discussed in some details. Further efforts are outlined to the future work.
LI Qingfeng, Dr. techn. professor in Department of Energy Conversion and Storage, Technical University of Denmark, received his PhD at Northeastern University of Shenyang, China in 1990. He initialized the HT-PEM research in Denmark and has coordinated/participated 7 EU and 25 Nordic research projects including a Danish-Chinese Centre on Proton Conducting Systems and a 4M Centre devoted to fundamental research om mechanism, materials, manufacturing and management of HT-PEMFCs. Professor Li has been involved in teaching 5 undergraduate courses and 6 graduate courses and supervised 19 phd. and more than 30 master students.
