  In this paper, dual-complex k-Pell numbers and dual-complex k-Pell
quaternions are defined. Also, some algebraic properties of dual-complex k-Pell
numbers and quaternions which are connected with dual-complex numbers and
k-Pell numbers are investigated. Furthermore, the Honsberger identity, the
d'Ocagne's identity, Binet's formula, Cassini's identity, Catalan's identity
for these quaternions are given.
