New Article "Benchmarking Fuel Cell Electrocatalysts Using Gas Diffusion Electrodes" published in ACS Energy Letters
24 January 2022
In an international collaboration, researchers at HI ERN have published a Gas Diffusion Electrodes (GDE) inter-lab comparison in the renowned journal ACS Energy Letters. In this work, the researchers show that comparable oxygen reduction reaction (ORR) catalyst benchmarking is possible with different GDE half-cells and in various laboratories. They set a benchmark for GDE testing with three commercial catalysts, propose best practices for successful GDE measurements and compare the various cell designs introduced in the literature so far. The paper provides an essential foundation for anyone working on GDE half-cells for fuel cell reactions.
