It is shown that in charge unbalanced double layer quantum Hall system with zero tunneling pseudospin Goldstone mode excitations form moving kink-soliton in weakly nonlinear limit. This charge-density localization moves with a velocity of gapless linear spin-wave mode and could be easily observed experimentally. We claim that mentioned Goldstone mode kink-solitons define diffusionless charge transport properties in double layer quantum Hall systems.
