The article discusses a groundbreaking strategy developed by researchers to enhance the performance of anion-exchange-membrane fuel cells (AEMFCs) using a novel quantum well-like catalytic structure (QWCS) containing quantum-confined metallic nickel nanoparticles. Traditional AEMFCs often face challenges due to the self-oxidation of non-precious metal catalysts, leading to cell failure. The newly designed QWCS, called Ni@C-MoOx, allows selective electron transfer, preventing electro-oxidation, and ensuring long-term stability of the fuel cells. The catalyst demonstrated remarkable performance, maintaining high power density and stability under rigorous conditions. This innovation could lead to the development of cost-effective, reliable AEMFCs, offering a promising solution to the limitations of current fuel cell technologies. The research highlights the potential of quantum confinement in enhancing catalytic activity and protecting non-precious metal catalysts from degradation, opening new avenues for advanced fuel cell designs.
