Towards the Numerical Solution of a Large Scale PDAE Constrained Optimization Problem Arising in Molten Carbonate Fuel Cell Modeling

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.
