CEI EN IEC 62282-8-101

This part of IEC 62282 addresses solid oxide cell (SOC) and stack assembly unit(s). It provides for testing systems, instruments and measuring methods to test the performance of SOC cell/stack assembly units for energy storage purposes. It assesses performance in fuel cell mode, in electrolysis mode and/or in reversible operation.

This document is not applicable to small button cells that are designed for SOC material testing and provide no practical means of reactant utilization measurement, or to single-chamber SOC. This document is not intended to be applied to fuel cell/stack assembly units for power generation purposes only, since this is covered in IEC TS 62282-7-2. Therefore, test methods are not included in this document that are applicable to fuel cell mode only and that are already described in IEC TS 62282-7-2.

This document is intended for data exchanges in commercial transactions between cell/stack manufacturers and system developers or for acquiring data on a cell or stack in order to estimate the performance of a system based on it. Users of this document may selectively execute test items suitable for their purposes from those described in this document. Users can also substitute selected test methods of this document with equivalent test methods of IEC TS 62282-7-2 for SOC operation in fuel cell mode only.

NOTE 1 In the context of this document, the term "reversible" does not refer to the thermodynamic meaning of an ideal process. It is common practice in the fuel cell community to call the operation mode of a solid oxide cell that alternates between fuel cell mode and electrolysis mode "reversible".

NOTE 2 This document considers only steam electrolysis. Other reactants in electrolysis mode can be used, provided appropriate measures are taken for handling the specific reactants and products, and the guidelines as regards the measurement, control and post-test analysis of results are adapted accordingly.
