Diagnostic d'une pile à combustible PEMFC. Une approche statistique

The diagnosis of a fuel cell for inboard applications, needs approches which could be applyed in real time and with a reduced number of sensors. In this article, we will present a statistic diagnosis approach for a fuel cell, in the absence of a model. The proposed approach is based in the analysis of statistical parameters of idividual cell voltages in the stack and in the definition of operating zones in a n dimension vector space defined by studied parameters.
