Summary

Cost effective manufacturing is a major concern for the development and commercialization of solid oxide fuel cells (SOFC). Costs are frequently compared for layer structures that differ in materials selection, manufacturing processes, and cell design. A meaningful cost model needs to consider all these parameters when deriving manufacturing cost estimates. Modeling tools are needed to aid in the selection of the appropriate process combination prior to making expensive investment decisions.

This paper describes the development of a performance based multi-process cost model. This model permits the comparison of manufacturing cost for different processing combinations and various materials while at the same time considering the effect of power density and operating temperature. the model consists of three parts: a performance model, a process yield model, and a process based cost model.

The results are summarized in cost performance maps. These maps indicate cost regimes for combinations of operating temperature and power density. the results show that SECA cost targets can be met for a judicious selection of performance and process parameters.
