The EPR of Mn^{2+}- or VO^{2+}-doped superprotonic conductor K_{3}H(SO_{4})_{2} is studied in the 80-471 K temperature range. VO^{2+} EPR spectrum reveals diffusion induced merging of proton transferred superhyperfine structure above 380 K. Line width anomaly is observed in Mn^{2+} EPR spectrum which is attributed to the intrabond and interbond proton motions, these lead to high protonic conductivity. It is shown that paramagnetic centers namely of electronic spin greater than 1, with excess charge compensated by the protonic vacancy, are good probes to monitor the protonic conductivity on molecular level.
