Water electrolysis is a promising technique for producing hydrogen, clean energy carrier essential achieving sustainable society. Reducing costs to meet the hydrogen demand anticipated through operations at high current density. However, excessive bubble formation during high-current deteriorates performance. Engineering substrates could help minimize additional overpotential while maintaining sufficient electrocatalyst amounts. In this study, we discuss optimizing porous maximize oxygen evolution reaction (OER) and overall single-cell performance, using Ni mesh model structure with or without NiFeOx catalyst decoration. The numerical simulation was conducted reveal contribution of an increase in electrode thickness, which augments quantities. calculation predicts that OER decreases stacking number electrodes. This estimation aligns experimental results when density 10 mA cmgeo–2. monotonic trend not observed 800 cmgeo–2, showing optimal thickness offers lowest potential. depends on electrocatalyst's identity; electrocatalysts lower Tafel slope (NiFeOx over Ni) require thinner electrodes maximum We optical characterizations track primary size. When comparing size aperture size, correlation between accumulation within stacked meshes thicker becomes evident. Our study underscores importance simultaneous development electrocatalysts, electrolytes, substrates.
