Abstract

The construction of cheap and efficient solid oxide fuel cells (SOFC) requires a detailed knowledge of currents, temperatures and mass flows. We analyze the behaviour of an SOFC modelling these quantities and varying the mechanical design and the adjustments at operation. The discretization approximates the conservation laws for energy, mass and charge and the nonlinear coupling of these quantities. The discrete equations are solved by a multigrid method, the coupling is handled by different exterior iterations.
