Abstract
During the operation of PEM fuel cells, problems can occur which lead to performance loss. A method called Nonlinear Frequency Response Analysis (NFRA), which has the potential to overcome such problems, is put forward. NFRA has originally been developed and applied to electrical systems and effectively used to analyze mechanical systems and chemical process systems. The theoretical work of Bensmann et al. has shown the applicability of NFRA for model discrimination in the kinetics of direct methanol fuel cells, while the work of Kadyk et al. has shown experimentally the applicability for distinguishing between fuel cell flooding, dehydration, and CO poisoning. Higher order frequency response functions are determined using a mathematical framework based on Volterra series evaluation of the responding signal and multidimensional Fourier transform of this series. Results of a study on the effect of CO poisoning on anode performance are elucidated. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA 2010 (Prague, Czech Republic 8/28/2010-9/1/2010).
