Deposition Processes

Two techniques of spray pyrolysis, namely, electrostatic and pneumatic spray deposition, were used to deposit samaria-doped ceria (SDC) electrolyte and lanthanum strontium cobalt ferrite (LSCF) cathode on cermet or metal supported anodes for solid oxide fuel cells (SOFCs) operated at reduced temperature. The deposition processes, the properties of the deposited films, and the electrochemical performances of the fabricated cells are reported in this paper. The deposited SDC electrolytes were dense and gas-tight, and had good adhesion to the underlying anodes. The deposited LSCF cathode had a preferred morphology to facilitate the transport of oxygen gas and effective contact with the electrolyte. Button cell testing indicated that the SOFCs with electrolyte or cathode deposited by spray pyrolysis had good electrochemical performance. This study demonstrated that spray pyrolysis is a cost-effective process for fabricating thin film SOFCs, especially metal supported SOFCs.

Capacity Method

Solid oxide fuel cells (SOFCs) are high-temperature, high-efficiency, combustionless electrochemical energy conversion devices that have potential for combined cycle applications. This paper intends to clarify and expand the efficiency discussions related to SOFC when operating in combined cycle (CC) systems. A brief analysis of the first and second thermodynamic laws is conducted and, building upon a previously developed SOFC dynamic model, operating fuel heating values are determined by utilizing the semi-empirical gas phase heat capacity method. As a result, accurate SOFC stack operational simulations are conducted to calculate its efficiency based on actual thermodynamic parameters. Furthermore, an analysis is conducted of a combined SOFC-CC system using dynamic modeling. Simulation results are given, which are intended to aid researchers in evaluating hybrid SOFC-CC generation systems.

AbstractIt is widely accepted that solid oxide fuel cells (SOFCs) represent a promising energy conversion approach that deliver a myriad of benefits including low environment pollution, high efficiency, and system compactness. This paper describes the construction of a basic model based on ohmic considerations, mass transfer, and kinetics that can effectively evaluate the performance of small button SOFCs. The analysis of the data indicates that there is a close alignment between the cell potential calculated using the model and previous experimental data. As such, it can be concluded that the model can be employed to optimize, evaluate, or control the design parameters within a SOFC system.
