本研究旨在開發適用於陰離子交換膜水電解器（Anion Exchange Membrane Water Electrolyzer， AEMWE）之高效能非貴金屬陰極電極。採用脈衝雷射結合熱還原製程，於鎳網基材上直接製備自支撐式NiMo觸媒，並探討不同前驅液濃度及載體材料對NiMo觸媒形貌與析氫反應（Hydrogen Evolution Reaction， HER）電化學性能之影響，進一步將所製備之NiMo自支撐陰極應用於AEMWE單電池測試。實驗結果顯示，不同前驅液濃度會影響NiMo觸媒於基材表面之覆蓋情形及其HER催化性能，經條件調整後可獲得較佳之電化學表現。載體比較結果顯示，以鎳網作為基材之NiMo自支撐電極具有較低之過電位及較佳之HER催化性能，且電化學交流阻抗分析結果顯示其具有較低之電荷轉移阻抗。最後將最佳化NiMo自支撐電極應用於AEMWE單電池中進行驗證，並以商業Pt/C電極作為對照組。在70 °C及1 M KOH操作條件下，全非貴金屬NiFeMn/NiMo單電池於2.0 V時可達1818.1 mA/cm²之電流密度。研究結果證實，自支撐NiMo電極具有良好之HER電化學性能，並展現其於高效能無鉑族AEMWE水電解製氫技術之應用潛力。;This study aims to develop a high-performance non-precious-metal cathode for anion exchange membrane water electrolyzers (AEMWE). A self-supported NiMo catalyst was directly fabricated on nickel mesh using a pulsed-laser-assisted thermal reduction process. The effects of precursor concentration and substrate material on the morphology and hydrogen evolution reaction (HER) performance of NiMo were investigated. The results showed that precursor concentration affected catalyst coverage and HER activity， while NiMo supported on nickel mesh exhibited lower overpotential and charge-transfer resistance. The optimized NiMo cathode was further applied to an AEMWE single cell and compared with commercial Pt/C.At 70 °C in 1 M KOH， the all-non-precious-metal NiFeMn/NiMo single cell reached a current density of 1818.1 mA/cm² at 2.0 V. These results demonstrate that the self-supported NiMo electrode has strong potential for high-performance non-precious-metal AEMWE applications.
