Electrochemical Engineering Science

Flow Cell ExperimentElectrochemical Engineering Science (EES) at Newcastle targets challenges in sustainable environment and energy and in healthcare, implementing multidisciplinary research  activities exploring applications of electrochemistry in energy storage, power generation, electrolysis, green energy, sensors and environmental protection and treatment applications. The group carries out novel research into fuel cells, batteries, hydrogen generation, electrolysers, biosensors and bioelectronics and carbon dioxide utilisation. The group also explores novel techniques in the synthesis of new catalyst, nanomaterials and membrane materials and optimising electrode structures.  More recently, the group have been using electrochemical analysis to understand cellular and microbial catalysis and processes and to develop also medical and health care applications.
