Reproducible characterization of SOFC single cell power density is important for various applications. Cell development requires accurate assignment of material parameters and electrochemical characteristics; and also benchmarking of different manufacturing technologies and suppliers needs simple test equipment that ensures reproducible test setups. In this regard, special emphasis is put on the gas-tight mechanical mounting including the essential gas supply and electrical connection of a MEA. Managing these important factors is guaranteed by so-called cell housings.

Mainly, cell housings are designed for tests and measurements at different planar fuel cell types, such as ESC, ASC and MSC. Electrolyte supported cells already have a high performance and good redox stability, anode supported cells (ASC) at higher performance still lack redox stability. Metal supported cells (MSC) are still under development but already feature positive redox stability and optimum characteristics for thermal cycling. Research and evaluation of these parameters play a decisive role in pushing forward market access of products using SOFC technologies.

With the development of the full-ceramic TrueXessory-HT, FuelCon responds to the demand of easy-to-handle test equipment that also ensures reproducible test setups. The use of ceramics as sole material eliminates negative impact on cell performance, for example through chrome contamination, and together with the perfected sealing concept of the even-grinded ceramic surfaces, allow a simple test setup as well as the best fuel and oxygen supply. Doing so, optimum conditions for reproducible cell performance testing can be achieved. The non-destructive concept of cell integration allows the application of various post mortem analysis methods.

The FuelCon cell housing is applicable for an active cell surface of 5x5 cm2. By using special adapter frames differing cell thickness of ASC and ESC can be compensated individually so that every cell can exactly be positioned in the housing. Varying thickness of electrodes can be balanced by application of nickel or platinum nets.

By applying an innovative compression system the TrueXessory-HT is also suitable for tests with varying compression forces. Through the balanced compression distribution in the cell housing compression conditions similar to a stack can be simulated on a single cell. The TrueXessory cell housing can be used with all MEA test stations of the Evaluator-HT series for which pre-defined and proven test program libraries are already available. Thus, FuelCon offers innovative solutions for short-term tests, material screening, long-term test and in-line quality management for all requirements of SOFC fuel cell technologies.

The development of the cell housing was carried out in close collaboration with the Fraunhofer Institute for Ceramic Technologies and Systems IKTS.
