ABSTRACT

Molten carbonate fuel cells (MCFCs) allow an efficient and environmentally friendly energy production by converting the chemical energy contained in the fuel gas in virtue of electro-chemical reactions. Their dynamical behavior can be described by large scale embedded systems of 1D or 2D nonlinear partial differential algebraic equations (PDAEs) up to dimension 28. They are of mixed parabolic-hyperbolic type with integral terms in the right hand side and initial and nonlinear boundary conditions, the latter governed by a system of ordinary differential equations.In this paper a new 2D model together with results of its numerical simulation is presented. The numerical results show a good correspondence with the expected dynamical behavior of MCFCs. The ultimate goal is to optimize this large scale nonlinear PDAE system to increase efficiency and service life of MCFCs. More... »
