Résumé

Stacking of cells in a SOFC stack requires that each element be perfectly flat and deprived, as much as possible, of internal stresses while maintaining their electrochemical capabilities. The EVOLVE concept introduces a metal foam based anode in which the foam plays the role of current collector, gas diffuser and thermo-mechanical deformation buffer. Owing to the different mechanical behaviour of the anode components, the deformation during sintering cannot be intuitively anticipated. Therefore, the global deformation of the cell was modelled and simulated by Finite Element considering a phenomenological approach of the anisotropic sintering. The thermo-mechanical parameters of each component were determined experimentally by dilatometry and three-point bending tests operated under conditions identical to those of the sintering. Results provide relevant indications on components composition and morphology, and on the sintering conditions for producing flat and stackable cells.
