摘要: Abstract The internal resistance of a PEM fuel cell depends on the operation conditions and current delivered by cell. This work's goal is to obtain semiempirical model able reproduce effect an individual commercial stack; perform statistical analysis in order study temperature inlet humidities parameters model. First, operating different was experimentally measured for DC currents, using high frequency intercept impedance spectra. Then, based Springer co-workers’ proposed. successfully experimental trends. Subsequently, curves versus obtained were fitted model, variance (ANOVA) performed determine which factors have statistically significant each parameter. Finally, response surface method applied regression
