**About the Editors**

#### **Jean St-Pierre**

Jean St-Pierre, PhD, PEng is a graduate of Polytechnique, Montreal, Canada. More than 25 ´ years of his career have been devoted to the development of proton exchange membrane fuel cells including aspects such as water management, freezing, degradation mechanisms, mathematical modeling, diagnosis and measurement methods, electrocatalysis, pure oxygen operation for space and air independent applications, and reactant stream unit operations (gas separation and fuel reforming catalysts). He previously held principal research scientist and research professor positions at, respectively, Ballard Power Systems (1995-2005) and the University of South Carolina (2006-2010). He is currently a researcher at the University of Hawaii – Manoa, and focuses on fuel cell and related technology activities. His work has led to more than 115 journal papers, book chapters, and conference proceedings, and to more than 30 granted, published, and provisional patents.

#### **Shangfeng Du**

Shangfeng Du (Associate Professor) leads the Low Temperature Fuel Cell and Electrolyser research group in the School of Chemical Engineering at the University of Birmingham. He received his BEng in Materials Science and Engineering from Tsinghua University, China in 1999, and his PhD in Chemical Engineering from the Institute of Process Engineering, Chinese Academy of Sciences, China in 2005. He has been a postdoctoral researcher in the Powder Metallurgy Laboratory (PML) at the Max Planck Institute for Metals Research before he joined Birmingham in 2007. His group is focused on electrochemical engineering research of catalyst electrodes that bridges the gap between novel catalyst nanostructures and high-power performance electrochemical devices. His research activities cover electrode structure design, 1D nanostructure development, and surface and interface characterization. He has been the author of one book, and published more than 60 journal papers, book chapters, and patents.
