Research area

The HSPE Department carries out fundamental and applied research in the field of electrochemical generation of hydrogen and energy in electrolytic cells, fuel cells and reversible bifunctional fuel cells with polymer electrolyte. The research activities include development of novel electrode materials (catalysts, catalyst supports) and components (gas diffusion electrodes, membrane electrode assemblies), their characterization, integration in model systems, and evaluation of cell performance under conditions close to the real working regimes. Multi-metallic, mixed metal-metal oxide and composite catalysts deposited on active catalytic supports are studied. New materials with low or zero platinum content, enhanced structural and chemical stability are synthesized and investigated. Laboratory scale prototypes of hydrogen energy systems and autonomous testing devices are designed and tested. The HSPE research team offers expertise in other fields of the electrochemical material science, too, such as corrosion and corrosion inhibitors, electrochemical sensors, functional electrical stimulation, glasses and glass-ceramic materials, sonochemistry.
