The study of electrocatalysis of the oxygen reduction reaction is related to the development of low-temperature fuel cells (see Scheme). The electrochemical reduction of oxygen occurs on the fuel cell cathode and platinum and its alloys are predominantly used as electrocatalysts for this process. The high price of Pt and its limited supply are the main factors that hinder the wider commercialization of fuel cells. For this reason we have carried out research to replace costly platinum with cheaper alternative catalysts. The basic requirements for novel and less expensive catalysts materials are high electrocatalytic activity towards oxygen reduction and good durability in fuel cell conditions. We have paid a great deal of attention to the determination of kinetic parameters for oxygen reduction on these non-precious metal catalysts.
Fuel cells, which operate at lower temperature than 100 ºC, are considered as attractive energy conversion devices in several fields, including automotive applications. Fuel cell technology is environmentally friendly, because the only product of fuel cell processes is water.
In 2010-2015 four PhD thesis have been defended (Nadežda Kongi, Marko Kullapere, Ivar Kruusenberg and Elo Kibena). We have published 50 papers in peer-reviewed Journals during this period.
