%X A single–pore model for performance of the cathode catalyst layer (CCL) in a PEM fuel cell is developed. The model takes into account oxygen transport though the CCL depth and through the thin Nafion film, separating the pore from Pt/C species. Analytical solution to model equations reveals the limiting current density $j^{lim}_{N}$ due to oxygen transport through the Nafion film. Further, $j^{lim}_{N}$ linearly depends of the CCL thickness, i.e., the thinner the CCL, the lower $j^{lim}_{N}$. This result may explain unexpected lowering of low–Pt loaded catalyst layers performance, which has been widely discussing in literature.
