The performance of current solid oxide fuel cells (SOFCs) was evaluated in terms of the cell designs and the physicochemical properties of the component materials such as the electrode and electrolyte in order to demonstrate the potentials of state-of-the-art SOFC technology for the widespread use of SOFCs. A flat tubular type SOFC stack for residential use was analyzed as a standard case of a production version in terms of stack volume, weight, and material cost. The power density and power generation efficiency were also evaluated by model estimation. A microtubular type SOFC was evaluated as an example of an advanced cell design. The assessment of the cell design can pinpoint performance advantages of the microtubular type in stack volume, weight, material cost, volumetric power density, and efficiency. In addition, we attempted to demonstrate an analysis for the concurrent comparison of the impact of cell designs and material properties on cell performance by using volumetric power density as a common assessment criterion. Through the assessment with the state-of-the-art SOFC technology, it is possible to make a quantitative comparison of the significances of cell design and material property. The present assessment suggests that the development of cell design is a consistent approach to improving cell and stack performance. In this way, the proposed assessment can provide hints to a reliable research strategy for improving cell performance and realizing the widespread use of SOFCs.

The Subject

Solid oxide fuel cells represent a potentially important application for ceramic materials. There are, however, some significant issues which can affect the reliability and durability of the cell. The generation of stresses and associated strains in fuel cells is an important concern that needs to be addressed in order to avoid mechanical failure of the cell. Few comprehensive studies have been published on the subject of stress analysis of planar and tubular SOFCs to-date, although various numerical methodologies have been used to obtaining the stress distribution in specific SOFC components over the last 10 years. The objective of this paper is to summarize the state-of-the art of solid oxide fuel cell stress analysis efforts so that the salient issues can be identified.

Viable Approach

High ionic conductivity of the electrolyte is a requisite for cheap, reliable and efficient solid oxide fuel cells. In this study we show that co-doping is not a viable approach to increase the conductivity of state-of-the-art electrolyte material, ceria.
