The aim of this study was to synthesize a novel catalyst for urea oxidation and test stacked membraneless direct fuel cell (DUFC) with raw urine as fuel. molybdenum nickel phosphides on foam (MoNiP/NF) were synthesized using combined hydrothermal phosphating method. honeycomb-like MoNiP/NF Mo/Ni molar ratio 0.50 (i.e., MoNiP/NF-0.50) showed the highest electrocatalytic activity among different catalysts. DUFC constructed MoNiP/NF-0.50 electrode anode gas diffusion cathode. With spacing 5 mm 6 pairs, had maximum voltage 0.55 V power density 0.115 mW cm–2 at external resistance 1000 Ω, which output 5.32 times higher than that in individual DUFC. removal reached 65.8% 100 Ω within 192 h. excellent performance could be attributed high catalyst, small spacing, multiple pairs. Our results should provide promising potential scalable efficient treatment.

Abstract Proton exchange membrane fuel cells (PEMFCs) have attracted significant research interest due to their ability generate only water and energy. PEMFCs operate based on the principle of redox reactions, which require a catalyst for individual half‐reactions. However, commonly used platinum (Pt)‐based catalysts are expensive, performance needs enhancement. In this study, an effective strategy is presented preparing Pt–rare earth nanoalloy catalysts, achieving improvements in catalytic while reducing costs. Additionally, through urea modification, novel carbon carrier (XC‐72) successfully developed, widely utilized as support cells. The Pt–Nd@HCN‐400 synthesized by combining newly developed with Pt–Nd alloy. Under standard cell operating conditions, exhibited 5% increase durability compared its unmodified counterpart. This study offers promising approach enhancing PEMFC catalysts.
