Modelling and Prediction of Deformation during Sintering of a Metal Foam Based SOFC (EVOLVE)
Owing to the very different nature and morphology of the anode components, the deformation during sintering cannot be readily anticipated. Therefore, the global deformation of the cell was modelled and simulated by Finite Element in order to optimize the shaping process. The modelling was achieved considering a phenomenological approach of the anisotropic sintering. Calculations of the deformation include morphological and mechanical characteristics of each layer as well as the dimension of the cell to anticipate any scale effects. 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.
