Abstract: Polymer electrolyte membrane (PEM) fuel cell has been regarded as a potential power source for various applications due to its noteworthy features of high efficiency and zero emission. Its performance and dynamics are controlled by electrochemically coupled transport processes, including fluid flow, phase change, species transport, energy conversion/transport, and proton/electron conduction. Water and thermal management play an important role in PEM fuel cell operation and durability. For examples, liquid water product needs to be effectively removed from the electrodes to avoid “flooding”. Ice formation during cold start will terminate fuel cell operation. In this talk, I will present recent progress of PEM fuel cell development and discuss several thermal-fluid fundamentals that the UC Irvine has original contributions, including:


  1. Two-phase flow in the fuel cell micro-channels: theory development and experiment.  
  2. Non-isothermal two-phase flow in gas diffusion layers: heat pipe effect, heterogeneity’s impacts, and two-phase flow in fibrous microstructures.
  3. A new reactant distributor: porous media flow field.
  4. Cold start: theory and experiment.
  5. Neutron radiography in PEM fuel cell applications.


BioYun Wang received his B.S. and M.S. degrees in Mechanics and Engineering Science from Peking University in 1998 and 2001, respectively. He went to the Pennsylvania State University where he received his Ph.D degree in Mechanical Engineering in Aug. 2006. Wang joined the MAE (Mechanical and Aerospace Engineering) faculty at the University of California, Irvine in July 2006. Wang has produced over 70 publications in PEM fuel cell, including a book on PEM Fuel Cell Water and Thermal Management Fundamentals in 2013 and a PEM fuel cell review paper in 2011 (which has been cited over 1,959 google scholar times). He received a few awards, including the prestigious Distinguished President's Award and Outstanding Educator Award from Orange County Engineering Council, the Seasky Scholarship from Dalian University of Technology, China, and the 2011-2012 Applied Energy Certificate of Excellence: Most Downloaded Authors. Several of his seminal works are highly cited in the major fuel cell journals. His 45 journal papers published in 2005-17 have been cited over 4,800 times.  Scopus (last access on 10/3/2018) shows one first-authored paper is the most cited in the history of Applied Energy since 1975 (among 12,590 papers). Wang served as Track chair/co-chair, session chair/co-chair, conference chair and committee member for many international conferences of fuel cells, thermal energy, and engineering. Wang is currently Professor at the UC Irvine and ASME Fellow.
