A demonstration pilot installation for advanced production of gas diffusion electrodes for metal-air batteries, being built at the Institute of Electrochemistry and Power Systems of BAS (IEES-BAS), was presented for the first time at the Sofia Science Festival 2022. Scientists at the institute are developing zinc-air, magnesium-air and lead-air batteries, with efforts focused on improving rechargeable metal-hydride-air batteries. The advantages of these batteries for stationary applications, including renewable energy storage, are low weight, low cost, safety in operation and the use of environmentally friendly materials. In addition to stationary applications, they can also be used as batteries in hybrid vehicles as they are lighter and have a higher capacity than the nickel-metal hydride batteries currently used. This fact is due to the unlimited capacity of [...]

A prototype of a trolleybus, which Bulgarian scientists of BAS are transforming into a hydrogen-powered transport vehicle, was shown to the EU Commissioner for Innovation, Research, Culture, Education and Youth Mariya Gabriel, the Executive Director of the public-private partnership “Clean Hydrogen” Bart Biebuyck, and the President of BAS Prof. Julian Revalski, Full Member of the Academy. The development of Bulgaria's first demonstration project for hydrogen deployment in transport was presented at “Levski” trolleybus depot. For the first time in Bulgaria the "retro fitting" method is applied to transform a trolleybus into a hydrogen electric vehicle. The trolleybus will not only be powered by overhead lines, but will also perform a 100-kilometre hydrogen run. The development is part of the implementation of the National Scientific Programme [...]

Research Assistant Dr. Krum Banov and Senior Assistant Dr. Borislava Mladenova from IEES-BAS are the winners of the competition for young scientists, which was held within Sofia Electrochemical Days SED `22. Krum Banov won the award for the best oral presentation and Borislava Mladenova made the best poster presentation. The prizes were awarded by the chairman of the international jury Prof. DSc Eng.  Martin Bojinov from UCTM-Sofia. The two young scientists received award plaques, diplomas from IEES-BAS and a one-time financial incentive from UCTM-Sofia. Sofia Electrochemical Days SED`22 were opened on 11 May by the President of BAS Prof. Julian Revalski, Full Member of the Academy. In his speech, he recalled the necessity of holding conferences to share knowledge between more experienced and young colleagues [...]
