We investigate spherical proton emitters in the region from I (Z=53) to Bi (Z=83) isotopes as a crucial application of the relativistic energy density functional PC-PK1 beyond the drip line. The continuum effect is treated carefully by using the relativistic continuum Hartree-Bogoliubov theory. We calculate the half-lives of the proton emitters using the Wentzel-Kramers-Brillouin (WKB) method and observe that the calculated values are in reasonable agreement with experimental results for most of emitters considered in this study. We also discuss a clue to improve the functional PC-PK1 in future.
