В работе описана оптимизация прибора Сивертса для точного измерения взаимодействия водорода с материалами волюметрическим методом. Целью настоящего исследования является снижение влияния температурного градиента в аппарате типа Сивертса для получения точных и достоверных результатов измерений кинетики сорбции и десорбции в материалах – накопителях водорода. Были рассмотрены два метода учета влияния температурного градиента на содержание водорода. Первый метод заключался в искусственной сегментации газового тракта и определении температуры в каждом сегменте. Второй метод заключался в представлении общего объема газового тракта как двух динамических объемов горячей и холодной части. Экспериментально были получены параметры уравнения для расчета содержания водорода с учетом влияния температурного градиента для обоих методов. Затем была проведена автоматизация процессов сбора данных и расчетов температурного градиента для данных методов и сравнение результатов по применению этих методов. Наилучший результат был достигнут с использованием второго метода: максимальное отклонение составило 0,1 масс.% от начального количества газа. Практическая значимость исследования заключается в повышении точности определения массовой доли водорода в исследуемых материалах в процессе сорбции в аппаратах типа Сивертса.

This paper discusses the optimization of the Sieverts-type apparatus with the goal of achieving precise measurements of the interaction between hydrogen and materials using volumetric methods. In order to obtain accurate and reliable measurements of sorption and desorption kinetics in hydrogen storage materials, it is important to reduce the effects of temperature gradients within the Sieverts-type apparatus. Two methods were developed to minimize the impact of temperature gradients on hydrogen measurements. The first method involved segmenting the gas path and measuring the temperature in each section. The second method utilized the total volume of the gas path, divided into two dynamic volumes for hot and cold sections. Experimental equations were derived to calculate the hydrogen content, taking into account the effects of temperature gradient, for both methods. These methods were then implemented, and the results were compared. The most successful result was obtained using the second method, with the maximum deviation of 0,1% of the initial gas volume.
