文摘

The parameter estimation of a molten carbonate fuel cell (MCFC) model is presented. The model is dynamic,spatially distributed, and describes a cross-flow configuration of the gas channels. It includes direct and indirectinternal reforming, a catalytic combustor, and a reversal chamber between the anode and the cathode. Theparameter estimation is based on measurements at a full-scale industrial MCFC plant. Because of the complexityof the model, the high number of parameters, and limited measurements, a specific strategy for the parameteradjustment has been developed. It includes a system balancing, sensitivity analysis and stepwise optimizationof single parameters and parameter groups.
