Abstract:	A dynamic, mathematical model of a proton-exchange-membrane fuel cell stack is presented. The model is time-dependent, one-dimensional along the channel and non-isothermal. It is based on energy and mass balance equations, an electrical and a membrane model. Heat and mass transfer by convection and conduction within the stack, as well as changes due to condensation and evaporation of water are taken into account. The electro-osmotic drag and diffusion of water through the membrane is accounted for. In contrast to previously published dynamic fuel cell models, the mathematical description is formulated as a coupled system of time-dependent partial differential equations. The mass and heat balance equations are reduced in such a way that the model accounts for the mass and heat flow at the gas inlet and outlet of the anode and cathode. The corresponding parameters are crucial for the use of the model in system simulation and easily accessible for model validation studies. The equations are solved using the ODE solver ode15s of Matlab. First simulation results are presented. They represent the behaviour of a fuel cell stack adequately, thereby proving that the modelling approach is appropriate.
