A new mechanism for the acceleration of ultra high energy cosmic rays (UHECRs) is presented here. It is based on the tunnel-ionization of neutral atoms approaching electrically charged stellar black holes and on the repulsion of the resulting positively charged atomic part by huge, long range electric fields. Energies above 1018 eV for these particles are calculated in a simple way by means of this one-by-one, all-electrical model. When this acceleration mechanism is combined with the supernova (SN) explosion in the galactic halo of the massive runaway stars expelled from the galactic disk, then the various results obtained are shown to be compatible with virtually all the main observational facts about these UHECRs. Among these facts, this model predicts nearly the correct values of the measured top energy of the UHECRs and their flux in a specified EeV energy range. It also explains the near isotropy of arrivals of these energetic particles to Earth, as it has recently been measured by the Auger Observatory.
