Abstract: Without combustion, molten carbonate fuel cells (MCFC) convert chemical energy contained in fuel and oxidizer to electric energy via electro-chemical reaction. Performance and service life of MCFCs depends on its operating temperature. So control of the operation temperature within a specified range and reducing temperature fluctuations is highly desirable. In a first step towards this goal numerical simulations are computed and an index analysis of the partial differential-algebraic equation system (PDAE) is given.
