Abstract : Hydrogen formed by cathodic polarization of a bright Pt electrode in CO-saturated 1M H2SO4 is shown to remain associated with the electrode for relatively long periods of time. Such hydrogen causes unusual opencircuit potential behavior after anodic pulses and can give characteristic hydrogen regions in anodic charging curves. Bringing the electrode potential to a value where hydrogen is normally thought to be absent does not assure that all the hydrogen is removed. (Author)
