The pursuit of room-temperature superconductivity has recently been dominated by the high-pressure phases of hydrogen-rich materials, such as Hu2083S and LaHu2081u2080. While these binary hydrides exhibit remarkably high critical temperatures (Tc), their stabilization often requires pressures exceeding 150 GPa, limiting their practical scope. In this work, I propose a novel ternary system, Yttrium-Carbon-Hydride (Y—C—H), as a promising candidate for high-Tc superconductivity at reduced pressures. Based on Density Functional Theory (DFT) and evolutionary algorithm predictions, I identify a clathrate-like, face-centered cubic phase with an approximate composition of YCu2080.u2082Hu2081u2080 that is dynamically stable above 50 GPa. My calculations indicate a strong electron-phonon coupling mechanism, primarily driven by the high-frequency hydrogen vibrations, leading to a predicted Tc of up to 220 K at 100 GPa. I further detail a comprehensive experimental synthesis protocol using a diamond anvil cell (DAC) with in-situ laser heating and characterization, providing a roadmap for the empirical validation of this theoretically proposed material.
