A numerical analysis of PEMFC stack assembly through a 3D finite element model

Feasibility of in-plane GDL structuration: Impact on current density distribution in large-area Proton Exchange Membrane Fuel Cells

“…Besides, a "hole" in the current density distribution can be observed in the central region of the cartographies. It is believed to be due to a post-assembly deflection in the center of the stack, as demonstrated by Carral et al [29]. Indeed, when assembling the 6 cells in a stack, a mass is applied before clamping the end plates on their edges.…”

Sobol's sensitivity analysis for a fuel cell stack assembly model with the aid of structure-selection techniques

“…(2), Sobol's method is used to estimate the sensitivity indices in Eq. (7) through (9). Here, a Monte Carlo algorithm is used to calculate the first-, second-, and total-order indices of each input parameter, and the effect of the input parameters on the output metrics is thereby revealed.…”

Analysis of the compression characteristics of a PEM stack, development of an equivalent spring model and recommendations for compression process improvements

“…Due to the compromises that need to be made when evaluating compression homogeneity with the use of the aforementioned hardware, many researchers have turned to finite element models [14,23,25]. However, in order to reduce computational time, the models need to be simplified and authors have found significant discrepancies between such models when compared to reality.…”
