Research Interests and Topics
Professor Yuan's research concerns analysis of heat and mass transfer and other transport phenomena in fuel cells (e.g., SOFCs – solid oxide fuel cells and PEMFCs – proton exchange membrane fuel cells), and associated heat exchangers as well as fuel reformers. Numerical calculation methods have been further developed to enable predictions of various transport processes in composite flow channels for fuel and oxidant in fuel cells; two-phase water flow and effects on PEMFC performance; internal reforming reactions in SOFCs; the electrochemical reactions in fuel cells and the methane catalytic reforming reactions in reformers, and their effects on energy and mass balances. Overall modelling procedures for stacks and heat exchangers are also included in the research.
The current research interests are focused on comprehensive understanding of chemical reactions and nano-/micro-structured porous material effects on various transport processes in various components of fuel cell systems.
The research activities have been supported by STEM (Swedish Energy Agency), VR (Swedish Research Council), VR-Sida, and ERC (European Research Council), etc.
