Regeneration of Pt sites by maintaining CO scavenging ability through precise construction of the surface and interface structure of the catalyst is the key to obtaining high-performance CO-resistant catalysts. Here, we used molybdenum carbide (MoC_x) as the support for Pt and introduced Ru single atoms (SA-Ru) at the Pt-MoC_x interface to jointly decrease the CO adsorption strength on Pt. More importantly, the MoC_x and SA-Ru are immune to CO poisoning, which continuously assists in the oxidation of adsorbed CO by generating oxygen species from water dissociation. These two effects combine to confer this anode catalyst (SA-Ru@Pt/MoC_x) remarkable CO tolerance and the ability to operate stably in fuel cell with high CO concentration (power output 85.5 mW cm^-2@20,000 ppm CO + H₂ - O₂), making it possible to directly use the cheap reformed hydrogen as the fuel for PEMFCs.23:T519,Abstract Zinc metal has emerged as a promising candidate for high‐capacity and low‐cost anodes in aqueous zinc‐ion batteries; nevertheless, it encounters serious obstacles, including low cycling stability and poor reversibility, caused by parasitic reactions and the formation of zinc dendrites. Herein, the study proposes a novel nonprotonic dimethylacetamide (DMAC)/ZnCl 2 /LiCl electrolyte that enables both solvation structural modulation of [ZnCl x ] 2‐x and the cationic electrostatic shielding effect of [Li(DMAC)] + by controlling the concentration of LiCl. The optimal concentration of LiCl electrolyte (0.28 m ), which results in the highest ratio of [ZnCl 3 ] − , strikes a balance between low desolvation energy and a high mass transfer rate while promoting homoepitaxial deposition of Zn (002). Moreover, inert [Li(DMAC)] + ions, which possess a lower reduction potential, preferentially adsorb onto zinc protrusions, mitigating the tip effect. Leveraging electrolyte engineering, the zinc deposition/stripping process results in impressive long‐term stability, surpassing 2,800 cycles, and the Zn||MnO 2 cell also achieves a stable lifespan extending beyond 1400 cycles. The research highlights the potential of LiCl as an additive in the modulation of water‐free electrolytes.
