Abstract

A method for determining a spatial distribution (Rcx,yf) of a parameter of interest (Rc) representative of a contact resistance between a bipolar plate and an adjacent electrode of an electrochemical cell, in which a spatial distribution (Rcx,yf) of the parameter of interest (Rc) is determined depending on the spatial distribution (Qx,ye) of a second thermal quantity (Qc) estimated beforehand from the spatial distribution (Tx,yc) of a set-point temperature (Tc) and from the spatial distribution (Dx,yr) of a first thermal quantity (Dr).
