Для более полного анализа дополнительно привлечена сканирующая электронная микроскопия, позволившая охарактеризовать морфологию поверхности материала и спектроскопия комбинационного рассеяния, с помощью которой оценивали количество дефектов в кристаллической структуре углерода, а также содержание аморфной фазы. Показана селективность электрохимических методов определения площади поверхности по отношению  к краевой плоскости графита, что может являться как преимуществом, так и недостатком, в зависимости от целей исследования. Выявлено, что применение классического метода низкотемпературной адсорбции газов далеко не всегда оправдано, ввиду сложности подбора корректной модели, описывающей исследуемую систему. Кроме того, при исследовании приведенным методом электродных материалов полученные данные будут сильно завышены из-за лучшей смачиваемости углеродного материала азотом, чем водой. Адсорбция красителей из водных растворов, по-видимому, является наиболее подходящим методом для определения смоченной поверхности материала, однако требует наличия большого числа образцов, характеризуется значительной погрешностью и может давать несколько завышенные результаты, хоть и меньшие, чем низкотемпературная адсорбция азота. </p></abstract><trans-abstract xml:lang="en"><p>In this paper, a comparative analysis of methods for determining the surface area in relation to electrode materials was carried out on the example of commercial carbon felts of various structures. For a more complete analysis, scanning electron microscopy and Raman spectroscopy methods were additionally used. It is shown that electrochemical methods for determining the surface area are selective with respect to the edge plane of graphite, which can be both an advantage and a disadvantage, depending on the objectives of the study. It is revealed that the use of the classical method of low-temperature adsorption of gases is not always justified due to the complexity of selecting the correct model describing the system under study. Adsorption of dyes from aqueous solutions seems to be the most suitable method for determining the wetted surface of the material, however, it requires large amounts of sample and is characterized  by a significant error. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>углеродное волокно</kwd><kwd>площадь поверхности</kwd><kwd>скорость переноса электронов</kwd><kwd>емкость двойного электрического слоя</kwd><kwd>базальная плоскость графита</kwd><kwd>краевая плоскость графита</kwd><kwd>адсорбция метиленового голубого</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbon fiber</kwd><kwd>surface area</kwd><kwd>electron transfer rate</kwd><kwd>capacity of the double electric layer</kwd><kwd>basal plane of graphite</kwd><kwd>edge plane of graphite</kwd><kwd>adsorption of methylene blue</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">We thank the staff of the Center for Collective Use of Scientific Equipment “Production and Application of Multifunctional Nanomaterials” of Tambov State Technical University for assistance in recording the Raman spectra of the studied samples.</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">Smith REG, Davies TJ, Baynes NDB, Nichols RJ.
