Abstract: This paper presents the results of a detailed characterization of a five-cell DMFC stack, obtained using a cubic experimental plan that was derived from design of experiments (DOE) methods. The results show that the operational behavior of a DMFC stack is mainly influenced by three independent input variables. Therefore four dimensional regression models were plotted against the input variables of temperature, electrical current density and the anode circuit's methanol concentration. The terms of these models were generated for the technically relevant operating range by applying a response surface methodology (RSM).The generated models constitute a suitable starting point for follow-up modeling work of complete DMFC systems. The detailed characterization of a DMFC stack with mathematical models as an output is not available in the literature, so a data base for DMFC modeling can be provided to the scientific community. Additionally an application-oriented method for the characterization of DMFC stacks is described, which is an important tool for simulation-based development of DMFC stacks and systems.
