“…Of these, the Plansee SE’s cell design has gained considerable attention, since it is manufactured by a combined sintering and deposition route, leading to a very thin electrolyte membrane being realized [25,26,27]. These cells have been manufactured on a pilot scale and achieve power densities comparable to their more mature ceramic SOFC counterparts [28].…”

Abstract:In this study we report on the development and operational data of a metal-supported solid oxide fuel cell with a thin film electrolyte under varying conditions. The metal-ceramic structure was developed for a mobile auxiliary power unit and offers power densities of 1 W/cm 2 at 800 • C, as well as robustness under mechanical, thermal and chemical stresses. A dense and thin yttria-doped zirconia layer was applied to a nanoporous nickel/zirconia anode using a scalable adapted gas-flow sputter process, which allowed the homogeneous coating of areas up to 100 cm 2 . The cell performance is presented for single cells and for stack operation, both in lightweight and stationary stack designs. The results from short-term operation indicate that this cell technology may be a very suitable alternative for mobile applications.

Metal‐supported solid oxide fuel cells (MSCs) offer certain strategic advantages over the more conventional solid oxide fuel cells (SOFCs), which comprise only ceramic materials. Since alloys such as ferritic steels are very similar in their coefficient of thermal expansion (CTE) with ceramic components, viz., cerias, zirconias, and nickel oxide doped with either of them, they could provide excellent thermal cyclability while maintaining a strong interlayer bond. Therefore, in an anode‐supported cell the entire NiO‐ceramic support can be replaced by a ferritic steel porous support—the catalytically active NiO is therefore, a functional layer only. A huge savings in materials cost is achievable, because cerias and zirconias [usually doped with Y, Gd, Sm rare earth (RE) elements] are considerably more expensive that ferritic steels. Lowering the capital costs for SOFCs is an extensive global undertaking with US Department of Energy (DOE) laying down targets such as ~$ 200/kW for the stack itself, in order for SOFCs to become competitive with grid power costs and to offer a power source that promises 24 × 7 power supply for critical applications. This will eventually lead to a premier electricity generation device in the distributed power space, with the highest known electrical efficiencies (>50%). MSCs need very robust, high precision, and cost‐effective manufacturing techniques, which are scalable to high volumes. One of the main goals in this review is to showcase some of the work done in this area since the last review (2010), and to assess the technology challenges, and new solutions that have emerged over the past few years.

“…Considerable progress both in fundamental and applied aspects in MS-SOFCs has been obtained in recent years. For example, micro combined heat and power (mCHP) unit based on the MS-SOFC has been demonstrated by Ceres Power [2], a plasma sprayed MS-SOFC stack delivered a power of 606 W at 42.4% fuel utilization has been put forward in the Institute of Nuclear Energy Research in Taiwan [3], the potential of MS-SOFC for mobile applications has also been demonstrated in Plansee [4].…”
