The longitudinal dynamics of protons in hydrogen-bonded chains is studied in the framework of a simple one-component one-dimensional model with a two-parameter doubly periodic symmetric on-site potential proposed by Zolotaryuk and Pnevmatikos (1990) under an external electric field and damping. The behavior of the ionic and bonding defects has been proved analytically and numerically to exhibit particle-like properties. Mobilities of the dc and ac driven defects have also been calculated with different methods. Small-amplitude oscillating solutions of breather and envelope solitons have been studied analytically and numerically.
