“…This enhances the interaction between the materials, resulting in better electrochemical activity and stability of the catalyst layer [112]. Also, the presence of doping components leads to an increase in the electrode-electrolyte interface, which contributes to lower resistance and improved conductivity and leads to an improvement in the overall performance of the fuel cell [115]. Heteroatom-doped graphenes and their derivatives can also exhibit catalytic properties comparable to classical Pt/C-type catalysts, which can significantly reduce the cost of FC due to the absence of expensive metals [122,123].…”
