Performance analysis of the solid oxide fuel cell-microgas turbine (SOFC-MGT) hybrid system has been made. We assume a fuel composition that is methane based with varying concentrations of other species that are expected to be present in biomass-derived gas streams in preparation for the study of biomass fueled SOFC-MGT hybrid system. This is based on the fact that the chemical composition of biomass fuel produced from different fuel production processes is diversified, i.e., in one case one chemical species rich in concentration and in another case another chemical species rich. In the analysis, the multistage model for internal reforming SOFC module developed previously with some modification is used. With this model, studies cover not only the performance of the hybrid system but also the spatial distributions of temperature and concentration of some chemical species inside the module, namely, in the cell stack and in the internal reformer.

Hybrid Configuration

Solid Oxide Fuel Cell (SOFC) developers are presently considering both internal and external reforming fuel cell designs. Generally, the endothermic reforming reaction and excess air through the cathode provide the cooling needed to remove waste heat from the fuel cell. Current information suggests that external reforming fuel cells will require a flow rate twice the amount necessary for internal reforming fuel cells. The increased airflow could negatively impact system performance. This paper compares the performance among various external reforming hybrid configurations and an internal reforming hybrid configuration. A system configuration that uses the reformer to cool a cathode recycle stream is introduced, and a system that uses interstage external reforming is proposed. Results show that the thermodynamic performance of these proposed concepts are an improvement over a base-concept external approach, and can be better than an internal reforming hybrid system, depending on the fuel cell cooling requirements.

The design of Solid Oxide Fuel Cell (SOFC) Hybrid Systems (HS) is usually based on the use of natural gas as fuel. However, the possibility of using other fuels such as biomass gasification, pyrolysis, fermentation, and coal gasification could potentially increase the market for SOFC Hybrid Systems. In this paper, the influence of fuel composition on both HS layout and performance is investigated. The analysis is based on a layout and a detailed simulation model of a Hybrid System based on Rolls-Royce Integrated Planar SOFC (IP-SOFC) technology fed with natural gas, previously developed by the authors. Particular attention has been given to the thermal management of the stack, the anode flow recirculation design and the turbine-compressor redesign, including safe surge margin operation conditions.
