Fig. 3: Reduced gravity gas-evolving electrolysis (0–1 g).

The average potential or current of all reduced-gravity electrolysis experiments under galvanostatic (a) and potentiostatic (b) control, respectively (data collected with centrifuge (filled) or stationary (unfilled) cells). Error bars represent the standard error of the mean. To remove the influence of cell-specific shifted baselines, the average % change from 1 g for each g-level was applied to the mean 1 g value; hence 1 g data points and g-levels where only a single data point was collected are not shown with error bars. Trends shown are calculated based on centrifuge data only and have an R² value of 0.848, 0.868, and 0.496 for 50, 75, and 100 mA cm^–2 respectively, and 0.651 for 2.075 V.
