Mayken Espinoza-Andaluz, Ph.D., is a full professor at Escuela Superior Politécnica del Litoral (ESPOL) and co-supervisor of Ph.D. students in Heat Transfer and Energy Systems at Lund University. He earned his Ph.D. in Heat Transfer from the Department of Energy Sciences at Lund University. His areas of research include renewable energy, fuel cells, proton-exchange membrane fuel cells (PEMFC), solid oxide fuel cells (SOFC), physical and chemical phenomena, energy efficiency, Lattice Boltzmann methods (LBM), and computational modeling. He is a reviewer for several international journals, including the International Journal of Energy Research, the International Journal of Hydrogen Energy, and Computers and Mathematics with Applications.
Ester Melo Vargas is a research assistant at Escuela Superior Politécnica del Litoral (ESPOL). Her research interests include data analysis and fault detection applied to fuel cells and quality analysis and lean manufacturing applied to productivity management. In addition, Ms. Melo is the author and co-author of scientific articles that have been presented at congresses, conferences, and scientific meetings. She received her bachelor’s degree in audit and management control ESPOL.
Jordy Santana-Villamar is a researcher with the Center of Renewable and Alternative Energy at Escuela Superior Politécnica del Litoral (ESPOL). His area of research is electrochemical tests to evaluate the performance in fuel cells and redox flow batteries applying EIS technique, sweep current, linear, and circular sweep voltammetry; expanded graphite-resin composite materials development with secondary fillers for bipolar plates; and modeling on transport phenomena. He has published several scientific papers in journals, including the International Journal of Hydrogen Energy, Journal of Electrochemical Society, and Energies. He has also participated in congresses, conferences, and meetings to present his research. He received his bachelor’s degree in mechanical engineering from ESPOL, obtaining a diploma of distinction in research.
