Abstract
A method for producing an electrochemical cell is provided, the method including determining a spatial distribution (kx,yf) of a parameter of interest (k) representative of a permeability of a diffusion layer of at least one electrode of a reference electrochemical cell in operation, the determining being performed by defining a spatial distribution (Tx,yc) of a set-point temperature (Tc) within the cell in operation, by measuring a spatial distribution (Dx,yr) of a first thermal quantity (Dr) representative of local removal of heat, by estimating a spatial distribution (Qx,ye) of a second thermal quantity (Qe) representative of local production of heat (Qe), and by determining the spatial distribution (kx/yf) depending on the estimated spatial distribution (Qx,ye), and the method further including producing the electrochemical cell based on the reference electrochemical cell and in which the parameter of interest (k) has the determined spatial distribution (kx,yf).
