Data-set on MEA performance, stability, CO2 conversion and methanol yield (D6.3)

The main goal of the Loter.CO2M project is to develop a one-step conversion technique of CO2 and water to high energy liquid organic fuels without the use of CRM (Critical raw materials). The technique pursued is a low temperature co-electrolysis using electrochemical cells based on the AEM membrane as the research done within the project has shown that for MEAs based on acidic PFSA membranes (e.g. Aquivion or Nafion) only PGM catalysts can combine proper activity and stability. Further work on PFSA membrane has therefore been omitted and the latest research has solely been focussed on development of non CRM catalysts aimed for AEM (anion exchange membrane) based MEAs. The development and screening of OER catalysts has been done at CNR-ITAE. Selected compositions have been manufactured in intermediate sized batches (3 g) and the most promising compositions has been manufactured in batch-sizes of 35 g. A cuprite-carbon black electrocatalyst has been selected for the CO2 reduction cathode catalyst.
