This work is devoted to the mathematical modeling and experimental studies of electric-current generation during hydrogen oxidation in microtubular (MT) solid oxide fuel cells (SOFCs). The technology of manufacturing fuel cells and the experimental technique are described. A mathematical model is constructed that describes the occurrence of chemical reactions and diffusion and heat-transfer processes. When verifying the model using the example of hydrogen oxidation in a temperature range of 600–850°C, kinetic parameters are determined that make it possible to achieve the best agreement between experimental and model data.
