SWEETHY single cell test harmonisation defines standardised procedures for preparing synthetic seawater and describes the benchmarking test cell and sample properties for testing anion exchange membrane water electrolyser (AEMWE) cells in the SWEETHY project. Finally, it sets the test conditions for activation, polarisation and degradation testing. This harmonised approach supports SWEETHY’s goals and proposes a public reference of testing procedure for direct seawater operation with reliable and comparable performance results. The single-cell test protocols developed within the SWEETHY project have been distributed to the SWEETHY-consortium. Additionally, the common AEMWE cell setup was delivered to the SWEETHY-partners who are involved in single-cell testing with synthetic seawater.
