The proton exchange membrane is a key component in the currently widely studied Proton Exchange Membrane Fuel Cells. In this paper a fully coupled three-dimensional dynamic numerical model of the membrane including all the physically relevant phenomena, i.e. ion transport, hydration-dependent conductivity and thermal effects is presented. The highly non-linear model is discretized by means of the Finite Element Method provided by the COMSOL Multiphysics® simulation environment.
