Hybrid power plants consisting of a gas turbine and solid oxide fuel cells (SOFC) promise high electrical efficiencies if both components are directly coupled and the SOFC is operated at elevated pressure. This contribution discusses various aspects

Hybrid power plants consisting of a gas turbine coupled with solid oxide fuel cells (SOFC) convert chemically bound energy into electrical energy. They can be operated at higher electrical efficiencies than conventional power plants. Theoretical stud
High temperature solid oxide fuel cell (SOFC) stacks are highly efficient and environmentally friendly electrochemical systems, which convert the chemical energy of fuel gases with oxygen from air directly into electrical energy. During operation of

In contrast to single cells the electrochemical processes, the resistances and the loss mechanisms of SOFC stacks are not well understood. The paper presents both experimental and modeling results of the electrochemical behavior of SOFC stacks with A
In this study it is theoretically analyzed how flue gas recirculation at the hydrogen electrode of solid oxide cells (SOC) systems effects fuel utilization and carbon formation. Interdepence between cell fuel utilization, system fuel utilization and

This paper describes the effect of enhanced operating pressure on power density and efficiency of SOFC. Experiments were carried out with planar anode-supported cells which were operated at 1073 K with an anode gas mixture of 30% H 2 and 70% N 2 . Pr

Understanding the mechanisms of performance degradation is of key importance for increasing the lifetime of solid oxide fuel cells (SOFC). The aim of this work is to achieve a deeper understanding of the processes leading to nickel oxidation at Ni/YS
In this paper the influence of pressure on the performance of solid oxide electrolysis cells is theoretically analyzed in a pressure range between 0.05 and 2 MPa. A previously validated electrochemical model of a solid oxide fuel cell stack is used t

A model of a hybrid power plant consisting of SOFC and a gas turbine is presented. Simulations are carried out for a different number of SOFC stacks while keeping the output power of the SOFC constant. Results show that the effect of stack number on

Fuel Cells.
This paper presents a multi-scale model of a solid oxide fuel cell (SOFC) stack consisting of five anode-supported cells. A two-dimensional isothermal elementary kinetic model is used to calculate the performance of single cells. Several of these mod
