Title:Challenges and Solutions to High Temperature Polymer Electrolyte Membrane Fuel Cells and Electrolysers
Time:Nov.7,2018
Place:F103, School of Mechanical Engineering
Host:SUI Sheng, Associate Professor (Institute of Fuel Cells)

Biography:
Qingfeng Li is a full professor in Department of Energy Conversion and Storage, Technical University of Denmark. He received his Ph.D. at Northeastern University of China in 1990 and was in 2006 awarded the Doctor of Technices in Denmark. He initialized the high temperature PEMFC research in Denmark and has coordinated/participated 7 EU and 25 Nordic research projects including a Danish-Chinese Centre on Proton Conducting Systems. For the time being Professor Li is leading a Danish research center focusing on fundamental research on mechanisms, materials, manufacturing and management of high temperature polymer fuel cells.

ABSTRACT:
High temperature operation of polymer electrolyte membrane fuel cells and electrolysers has in last years motivated extensive research activities with great progress. In this talk, significant efforts and recent progress are first presented. The recognized critical issues include platinum based catalysts, acid retention and long term durability. Excellent polymer durability was observed under continuous operation in the mild temperature range. With load or thermal cycling, the durability issues are more critical due to the increased acid loss and catalyst degradation particularly under open circuit voltage operation. Further efforts are outlined to the future work.
