Proton‐conducting composite salts were obtained by doping uracil (U) with monodecyl phosphate (MDP). The proton‐transfer reaction of the composite salt involves the lactam form of U at low MDP doping ratios, and the lactim form at high ratios (see picture). A proton conductivity of 6×10 −4 S cm −1 was achieved at 160 °C under anhydrous conditions, and the material is thus of interest for applications in polymer electrolyte membrane fuel cells.
