O autorze

Dr. Samuel Cruz-Manzo is a research fellow from the University of Lincoln, UK with a solid understanding of electrochemical impedance spectroscopy (EIS) in polymer electrolyte membrane fuel cells (PEMFCs) and has also worked with EIS and modelling in Nickel-metal hydride and Lithium-ion batteries. Dr. Cruz-Manzo has experience in real-time dynamic modelling and diagnostic of failures in industrial gas turbines on projects funded by Siemens Energy, Lincoln, UK and previously worked as a simulation engineer at a UK fuel cell company (Intelligent Energy Ltd.). He obtained his PhD degree at Loughborough University UK with a research project related to EIS modelling in PEMFCs. During his PhD study Dr. Cruz-Manzo obtained a prestigious international student research award in Fuel Cells, the Fuel Cell Baker Award 2013, USA Dr. Paul Greenwood is a research engineer from the Abastecedora Electrica Tehuacan, Mexico and his interests include the performance analysis of electrochemical systems through EIS and modelling. Dr. Greenwood has obtained a PhD degree in Loughborough University UK with a research project related to enhancement of flow field plates in PEMFCs.
