This monolithic architecture integrates the catalyst layer with the porous transport layer (PTL) into a single conductive scaffold, thus eliminating the discrete PTL–CL interface and enabling binder-free operation. In three-electrode tests, the NFF exhibited an overpotential of 249 mV at 10 mA cm−2, Tafel slope of 33.4 mV dec−1, outperformed conventional Ni foam and stainless-steel fiber paper. When integrated into AEMWE modules, the anode delivered 927.9 mA cm−2 at 2.0 V and 25 °C, whereas at 70 °C under cathode-dry operation, NFF reached 1.857 A cm−2. A stability test showed negligible degradation after 60 h of intermittent day–night cycling at 600 mA cm−2 and after 5000 accelerated stress test (AST) square-wave cycles between 500 and 100 mA cm−2, demonstrating robust operation under renewable-energy-relevant fluctuations. These results establish tape-casted NFF as a scalable, high-performance anode platform that redefines AEMWE architecture for durable and efficient hydrogen production.falseAnion exchange membrane water electrolysisNiFe foamOxygen evolution reactionTape castingjournal article10.1016/j.fuel.2025.1380602-s2.0-105025116735
