“…Moreover, the stack design, materials and the operating conditions of the literature sources are often very different which makes the comparison of the results difficult. However, the data of Comminges et al (18) (36). The results of the current-voltage curves and the EIS spectra of the different partners are very reproducible (25,37) and in good agreement with the results of the present paper.…”

High temperature solid oxide fuel cell (SOFC) stacks are highly efficient and environmentally friendly electrochemical systems, which convert the chemical energy of fuel gases with oxygen from air directly into electrical energy. During operation of SOFC stacks under system operating conditions pronounced temperature and fuel gas composition gradients along the cell area and along the height of the stack occur. Therefore, in contrast to SOFC cells, the electrochemical behavior of SOFC stacks is much more complex and has not sufficiently been studied. Specially, a shortcoming exists in terms of understanding the homogeneity, performance loss mechanisms, and various resistances and overvoltages within the stack repeat components. Therefore, this paper focuses on the improvement of the understanding and of the interpretation of different current-voltage curves of solid oxide fuel cell stack repeat units. Three different cases are discussed: repeat units with high power performance, with high cell contact resistance and with high fuel utilization. The stacks were investigated by current-voltage curves, electrochemical impedance spectroscopy and gas analysis. In order to understand the electrochemical behavior of these three cases both experimental and modeling results are presented, compared and discussed.

“…For the development of the test procedures it is necessary to use reproducible SOC stacks which fit as best as possible to the test stations of the different test laboratories. Therefore, detailed specification lists of SOC stacks of different stack suppliers 27 and of the test stations of the project partners [28][29][30] were established and compiled. For the validation of the test modules it was decided to use SOFC/SOEC short stacks in the light weight design with 5 repeat units (RUs).…”

“…For each campaign, all short stacks were fabricated by ElringKlinger AG in one batch, which ensures a high reproducibility with performance differences between the stacks below 5%. 27 Figure 2 shows the experimental setup for the electrochemical characterization of the SOC stacks. In the first step, the interfaces between the SOC stack and the test station were specified, ideally as close as possible to the stack hardware boundaries, e.g.…”

In the EU-funded project "Solid oxide cell and stack testing and quality assurance" (SOCTESQA), standardized and industry wide test modules and programs for high temperature solid oxide cells and stacks are being developed. These test procedures can be applied for the fuel cell (SOFC), the electrolysis (SOEC) and in the combined SOFC/SOEC mode. In order to optimize the test modules the project partners have tested identical SOC stacks with the same test programs in several testing campaigns. Altogether 10 pre-normative test modules were developed: Start-up, currentvoltage characteristics, electrochemical impedance spectroscopy, reactant utilization, reactant gas composition, temperature sensitivity, operation at constant current, operation at varying current, thermal cycling and shut-down. The test modules were validated by comparing the results in terms of repeatability of the different testing campaigns and in terms of reproducibility among the different partners. Moreover, the results are discussed in context to the test input parameters.
