MIT News  October 8, 2024 The adverse effects of electrochemical bubbles on the performance of gas-evolving electrodes are well known. However, studies on the degree of adhered bubble-caused inactivation, and how inactivation changes during bubble evolution are limited. A team of researchers in the US (MIT, University of Chicago, Argonne National Laboratory) studied electrode inactivation caused by oxygen evolution while using surface engineering to control bubble formation. They found that the inactivation of the entire projected area was poor approximation which led to non-physical results. They analyzed large quantities of experimental data, to show that bubble impacts were small for […]
