Основное внимание уделено использованию высокотемпературных стеклянных герметиков, обеспечивающих герметичность конструкции. В статье описаны материалы и методы изготовления модельных топливных ячеек, включая различные комбинации электролитов (YSZ, ScSZ, GDC) и электродов (NiO, LSM). Конструкция исследовательских ячеек включает электрохимические сенсоры, обеспечивающие точный контроль состава газовой смеси, поступающей в активную зону, с отклонениями, не превышающими 0,5%. Результаты исследований вольт-амперных характеристик модельных ТОТЭ в температурном диапазоне 700–950 ℃ показали, что повышение температуры приводит к снижению омических потерь и улучшению кинетики электрохимических реакций. Максимальная плотность мощности достигается при более высоких плотностях тока с увеличением температуры, что объясняется повышенной проводимостью материалов и улучшенной активностью электродов. При более низких температурах наблюдается ограниченная эффективность ячеек из-за увеличенного сопротивления электролита и сниженной активности электродов. Разработанные исследовательские ячейки продемонстрировали высокую надежность и воспроизводимость данных, что позволяет использовать их для оптимизации состава материалов и структуры ТОТЭ. Полученные результаты подтверждают потенциал предложенной методологии для разработки высокоэффективных топливных элементов.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to the development and creation of research cells for solid oxide fuel cells (SOFCs) designed to study their characteristics at various temperatures. The primary focus is on the use of high-temperature glass sealants that ensure the hermeticity of the structure. The paper describes the materials and methods for fabricating model fuel cells, including various combinations of electrolytes (YSZ, ScSZ, GDC) and electrodes (NiO, LSM). The design of the research cells incorporates electrochemical sensors, providing precise control over the composition of the gas mixture entering the active zone, with deviations not exceeding 0.5%. The results of current-voltage characteristics of the model SOFCs in the temperature range of 700–950 ℃ showed that an increase in temperature leads to a reduction in ohmic losses and improved kinetics of electrochemical reactions. The maximum power density is achieved at higher current densities with increasing temperature, which is attributed to enhanced material conductivity and improved electrode activity. At lower temperatures, limited cell efficiency is observed due to increased electrolyte resistance and reduced electrode activity. The developed research cells demonstrated high reliability and reproducibility of data, enabling their use in optimizing the material composition and structure of SOFCs. The obtained results confirm the potential of the proposed methodology for the development of highly efficient fuel cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>твердооксидные топливные элементы</kwd><kwd>модельные топливные ячейки</kwd><kwd>исследовательские ячейки</kwd><kwd>высокотемпературные стеклянные герметики</kwd><kwd>электрохимические сенсоры</kwd><kwd>вольт-амперные характеристики</kwd><kwd>плотность мощности</kwd><kwd>омические потери</kwd><kwd>кинетика электрохимических реакций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>solid oxide fuel cells</kwd><kwd>model fuel cells</kwd><kwd>research cells</kwd><kwd>high-temperature glass sealants</kwd><kwd>electrochemical sensors</kwd><kwd>current-voltage characteristics</kwd><kwd>power density</kwd><kwd>ohmic losses</kwd><kwd>kinetics of electrochemical reactions</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>The work was fulfilled in the framework of targeted financing program No. BR21882359, supported by the Ministry of Science and Higher Education of Kazakhstan.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Le T.T., Sharma P., Bora B.J., Tran V.D., Truong T.H., Le H.C., Nguyen P.Q.P.
