dc.description.abstractAn advanced computational reactive flow code has been implemented into Mathematica® to analyze (electro-)chemical conversions and various transport phenomena in the Hexis® SOFC-stack. The finite element approximation is applied for the space discretization of the continuity equations. The convection dominant cases are stabilized by the SUPG (Streamline Upwind Petrov Galerkin) method. The fluid flow in the interconnect channels is derived analytically with accurate representation of the slip velocity on the porous electrode surfaces. The mathematical system is linearized by means of a pseudo-time step discretization via a semi-implicit scheme. This stable iterative procedure is applied to an evolutionary problem and it converges unconditionally to the steady solution. Due to the low aspect ratio of the thickness to the cross-section of the cell, a one-dimensional model of the cell is coupled with the flow inside the gas channels. This approach reduces the computing time by retaining the main geometric details.de_CH
