Conventional studies emphasize high surface area and porosity while neglecting local geometric curvature and connectivity. Here we identify local electrode curvature as a physically grounded descriptor. Positive curvature at sharp tips concentrates the electric field, raises local gas supersaturation, and reduces the three\u2010phase contact line pinning, which confines growing bubbles and enables their release at a small size. Flat or concave surfaces lack these effects and trap gas. To validate this, positive curvature (\u03ba\n                    <jats:sub>+<\/jats:sub>\n                    ) nanoneedles (NN), near\u2010zero curvature (\u03ba\n                    <jats:sub>0<\/jats:sub>\n                    ) nanosheets (NS), and negative curvature (\u03ba\n                    <jats:sub>\u2212<\/jats:sub>\n                    ) microporous (MP) electrodes are developed.

NS delivers moderate bubble behavior and an intermediate overpotential (248.04\u00a0mV), while MP suffers severe bubble pinning despite a moderate 60\u00a0\u00b5m bubble size, resulting in the highest mass transport overpotential (252.98\u00a0mV). This work verifies that open convex architectures govern bubble kinetics far beyond porosity, providing universal design guidelines for high\u2010performance OER electrocatalysts.\n
