|Institute of Electrochemistry and Energy Systems|
IEES is located in Sofia, Bulgaria. It has 120 employees, 62 of them a scientific staff. The main topics of the scientific activities are: fundamental electrochemical studies; research and development of electrochemical energy sources and information systems; electrochemical materials science; nano-scaled materials, electrochemical methods, techniques and instrumentation; development and application of e-Science tools.
IEES is a host organization of (i) European Internet Centre for Impedance Spectroscopy (EICIS), created for efficient dissemination and exchange of knowledge, experience and innovations in the field of Electrochemical Impedance Spectroscopy, (ii) COSENT – regional Cooperation of Southeast Europe for Nano- Technologies; (iii) TK64 – Technical Committee for harmonization of the Bulgarian standards for batteries with the European ones; (iv) Centre for Innovations. IEES is a member of the Bulgarian Hydrogen Society and BG GRID Society, organizer of “BG Joint Excellence Centres”. From 2003 IEES became a Centre of Excellence on Portable and Emergency Energy Sources under a contract with the European Commission. IEES has collaboration and contracts with: Commission of the European Community (FP4-6), UNESCO, IUPAC (“Definitions, Nomenclature and Data Exchange Formats for EIS”-coordinator); JRC - Institute for Energy (Petten, The Netherlands), NSF-USA (Kansas University), CNRS (LISE-Paris), University L. Pasteur (Strasbourg), Royal Society (Imperial College), and with private companies from USA, Norway, Germany, Japan.The Institute’s equipment includes heavy scientific instruments, testing stations and impedance working places. It is equipped with the necessary instrumentation, which is used for IEES tasks in this project.
IEES participates in IDEAL-Cell with principal investigators from the Department of Electrochemical Methods. They have a long and proven experience in: fundamental research, development and application of advanced methods for investigation and testing of energy sources (heavy pulse testing, Non-stationary methods, original Differential Coulometry Spectroscopy). The method of Electrochemical Impedance Spectroscopy is under continuous development - a set of new techniques for non-stationary investigations and data analysis is created. The advanced method of the Differential Impedance Analysis (DIA), developed by Z. Stoynov, is carefully approbated and disseminated, including the edition of an original monograph (Z. Stoynov, D. Vladikova). The successful collaboration with one of the partners (CNR), based on DIA, contributed to the discovery of new experimental facts and deeper understanding of the cathode reaction mechanisms in SOFC, bringing to new ideas for its optimization. This experience will be used in this project. A research priority of the group is also the development and implementation of e-Science instruments for efficient collaboration and virtual research in the field of Electrochemical Impedance Spectroscopy, which will support the implementation of the project.
