The solitonic mechanism for the protonic transfer is used to calculate a mobility of domain walls in hydrogen-bonded ferroelectrics. A one-dimensional model is considered. It is assumed that the sequence of proton jumps in double-minimum wells of hydrogen bonds brings about a domain wall motion. Calculations carried out for KH2PO4 crystals can explain the high mobility of domain walls in these substances.
