Membrane Systems for Hydrogen Production offers an overview of advanced technologies in the field of both catalysts and membrane technologies for hydrogen productions and energy saving. Catalysts play an irreplaceable role in chemical engineering for carrying out reaction at industrial level. Membrane processes are today well-recognized technologies in many fields, such as water and wastewater treatment, gas separation and purification, etc. This book relates these two fields and their role in electrochemical hydrogen production by presenting 5 specific chapters where the catalysts are compared to the membrane technology. The purpose of this book is to provide an overview on recently developed catalysts which work in combination with membrane operations for energy savings. This combination provides an example of strategies for engineering development and process intensification of interest for both industrial and developing countries.
