By using CFD methods, we carried out simulation of the phenomena occurring in the hydrogen-air fuel cell. As a result of this modeling we obtained the calculated discharge curves data of two fuel cells with two cathodes catalysts types 20Pt?-??? (0.42 mgPt/cm2) commercial catalyst and catalytic system synthesized on carbon nanotubes (CNT+15%??72). The calculated values do agree with the experimental data. The calculations made in accordance with the mathematical model have showed that the nanostructured synthesized catalyst is more stable than the commercial one under prolonged testing. Synthesized CNT-based catalyst systems can be a good alternative to the commercial catalysts.
