A model consisting in two quantum XX spin chains, one homogeneous and thesecond with random couplings drawn from a binary distribution, is considered.The two chains are coupled to two different non-local thermal baths and theirdynamics is governed by a Lindblad equation. In the steady state, a current Jis induced between the two chains by coupling them together by their edges andimposing different chemical potentials $\mu$ to the two baths. While a regimeof linear characteristics J versus $\Delta$$\mu$ is observed in the absence ofrandomness, a gap opens as the disorder strength is increased. In theinfinite-randomness limit, this behavior is related to the density of states ofthe localized states contributing to the current. The conductance is shown todiverge in this limit.
