Abstract	:	The performance can be lost depending on the concentration and type ofreformate components. Gas crossover in PEMFCs can also cause performance loss andthese effects are also presented. Impurities such as acetone coming from composite stackcomponents and sealants can also deteriorate the performance severely. Electrochemicalimpedance spectroscopy (EIS) is used as a diagnostic tool to study the impuritypoisoning.Reformate contains N2 and C02 and these components affect performancedifferently. These effects were quantified using anode overvoltage. Data for anodeovervoltage shows that C02 yields a significant poisoning effect (about 30 mV) on a Ptelectrode. Cyclic voltammetry (CV) data showed,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
