The effect of the structure and the specific surface area of carbon materials, contained in positive electrodes, on the peculiarities of cycling of lithium-sulfur cells (the depth of electrochemical reduction of sulfur and lithium polysulfides, the changes in capacity and Coulomb efficiency of cycling) was studied.

This work considers the application of graphene while forming the electrodes in biofuel cells. Graphene displays a number of important characteristics including first of all good mechanical properties, high thermal conductivity, high specific surface area, biocompatibility, structural peculiarities of a molecule, is available for chemical modification of the structure. Fabrication, properties of graphene and its oxide were considered and the peculiarities of the application of graphene as a basic material for electrodes in biofuel cells are also discussed.

Using complex models, including the solution percolation problem and electrochemical kinetics calculations are considered the features of a solid polymer fuel cell catalyst layers with a catalyst based on nanoscale carbon materials, including graphene nanowires. These calculations are consistent with the experimental data presented by optimizing the composition of the catalyst layers. It is shown that the addition of 20 wt.\% nanofibres graphene can reduce ohmic losses from the ion current and improve the performance of the fuel cell is 20%
