This deliverable defines the operating procedures of the SELECTCO2 project. It contains a wide variety of information relating to meeting dates and structures, internal communications, financial management and procedures for deliverables, milestones, and project reviews. This is a living document and will be reviewed at least annually to see if any necessary modifications are needed.
This report sets the standard operating parameters for testing electrochemical CO2 reduction catalysts, gas diffusion electrodes, and membranes used in the SELECTCO2 project. The purpose of this report is to allow for a set of conditions all partners can use as a guide to ensure consistency among different partners. While these guidelines are primarily meant to be used for consistency among SELECTCO2 partners, the consortium welcomes other entities to use these parameters as well to achieve consistency throughout the entire electrochemical CO2 reduction field. It should be noted that this is a living document and may be modified if deemed necessary by the consortium.

Abstract: In this work, the effect of ion-selective membranes on the detailed carbon balance was systematically analyzed for high-rate CO2 reduction in GDE-type flow electrolyzers. By using different ion-selective membranes, we show nearly identical catalytic selectivity for CO2 reduction, which is primarily due to a similar local reaction environment created at the cathode/electrolyte interface via the introduction of a catholyte layer. In addition, based on a systematic exploration of gases released from electrolytes and the dynamic change of electrolyte speciation, we demonstrate the explicit discrepancy in carbon
balance paths for the captured CO2 at the cathode/catholyte interface via reaction with OH when using different ion-selective membranes: (i) the captured CO2 could be transported through an anion exchange membrane in the form of CO32-, subsequently releasing CO2 along with O2 in the anolyte, and (ii) with a cation exchange membrane, the captured CO2 would be accumulated in the catholyte in the form of CO32-, while (iii) with the use of a bipolar membrane, the captured CO2 could be released at the catholyte/membrane interface in the form of gaseous CO2. The unique carbon balance path for each type of membrane is linked to ion species transported through the membranes.
