Summary: In this study, a new template-assisted electrospinning/electrospraying (E/E) technique was developed to fabricate organized-structured nanofiber/nanoparticle electrodes with well-defined 3D hexagonal patterned arrays of various sizes. The 80 mm diameter hexagonal patterned electrodes showed higher fuel cell power densities and electrochemical surface areas compared to random electrodes, with improved mechanical stiffness and platinum utilization. The E/E technique provides a versatile platform for investigating the effect of pattern type and size on fuel cell platinum utilization under ultra-low platinum loadings.
