It took us quite some time to bring this work to the end, but now we proudly present our GDE inter-lab comparison in ACS Energy Letters. In this work, we show, that comparable ORR catalyst benchmarking is possible with different GDE half-cells and in various laboratories. We set a benchmark for GDE testing with three commercial catalysts, we propose Best Practices for successful GDE measurements and we compare the various cell designs introduced in the literature so far. A must-read for everyone working on GDE half-cell setups for fuel cell reactions.
