Fig. 6

Adaptive ML predictions of i at 0.7 V and 75% RH for a grooved electrode with I/C = 1.2, a groove period of 3 µm and 0.3 mgPt cm−2 cathode loading. The black and red circles represent the experimentally measured performance of the flat and grooved electrodes, respectively. The parameters h and d1 of the grooved electrode are defined schematically at the top of the figure.
