Summary: A nonlinear boundary value problem (BVP) from the modelling of the transport phenomena in the cathode catalyst layer of a one-dimensional half-cell single-phase model for proton exchange membrane (PEM) fuel cells, derived from the 3D model of T. Zhou and H. T. Liu [in: Proceeding of the ASME Heat Transfer Division, 43–49, Orlando, Fla, USA, 2000 (2000); Int. J. Transport Phenomena 3, No. 3, 177–198 (2001)], is studied. It is a BVP for a system of three coupled ordinary differential equations of second order. Schauder’s fixed point theorem is applied to show the existence of a solution in the Sobolev space \(H^{1}\).
