Unveiling Bubble Dynamics of Proton Exchange Membrane Water Electrolysis at Elevated Temperatures
This work directly visualizes bubble dynamics in a proton‐exchange membrane water electrolyzer operated at temperatures up to 120°C and pressures up to 100 bar. Elevated‐temperature operation beyond the atmospheric boiling point markedly reduces bubble coverage, leading to lower bubble‐related voltage losses and enhancing cell performance.
