Abstract

For the validation of the test modules and programs the solid oxide fuel/electrolysis cell short stack assembly unit has to be specified and defined among the partners of the SOCTESQA project. Due to the higher impact of the hydrogen and fuel cell technology to the market penetration, system relevant testing samples are preferred in this project. If possible, it is aimed to use one uniform test sample for all work packages, e.g. a 3- or 5-cell short stack in the planar design. In order to decide which test specimen will be used in this project a list of generic SOC specifications is very useful. Therefore, this deliverable contains an overview with the most important generic SOC stack specifications. This list will be sent to the stack suppliers, in order to fill in the specifications of their SOC stack. By comparing the filled in lists of the stack suppliers with the test station capabilities of the project partners, the most suitable stack supplier for the procurement of the test assembly units will be selected. Due to confidential reasons with the stack suppliers, this public deliverable does not contain the detailed technical specifications of the SOC stack manufacturers but only the generic ones. The relevant SOC active cell size should be in the range of 100 cm2. The cells are anode supported (ASC) or electrolyte supported (ESC). The specification of the short stack comprises compulsory data like flow design, active area, cell design, electrical power, fuel utilization, mechanical load, heating rate, cooling procedure, maximum temperature, maximum current density and minimum (SOFC) / maximum (SOEC) voltage. Where possible, also the properties of the used components, e.g. bipolar plates, protective layers, contact materials and cell components are specified. Another important issue is the definition of the interfaces between test sample and test station. The stack interface (connectors, terminals, etc.) will depend on the manufacturer's choice. Although WP2 will specify the interface between the test device used to perform stack tests using stacks made available to the testing partner in this project, the project scope does not extend to harmonise any technical interface between stack and test equipment.
