From: Bubble dynamics matters at high-rate water electrolysis
a SEM, confocal laser scanning microscope photograph, and surface height information of felt, mat mesh with sieves of 1250 and square hole mesh with sieves of 60. Scale bar: 100 μm. b The amount of water collected at the cathode across the membrane as a function of time for AMEWEs with different stainless steel electrode designs. c Bubble behaviors in different stainless steel electrode designs. (operating conditions: room temperature (25 ± 2 °C), 0.4 A cm−2, three electrode H-cell tests, in-plane direction parallel to the ground). Scale bar: 400 μm. d The distribution of bubble sizes counted in high-speed camera images. Source data are provided as a Source Data file.
