We present the experimental results for Nb/Au/YBaCuO structures, in which the current flows along (001) direction of YBaCuO film. The theoretical evaluations show, that at the experimental values of the Au/YBaCuO interface transparency, determined from the interface resistance D~10-6, the critical current of the structure is of the fluctuation order of magnitude due to the sharp decrease of the amplitude potential of the superconducting carriers on this interface. Obtained I-V-curves could be interpreted in terms of contact between d-type pairing superconductor or gapless isotropic superconductor with normal metal. No critical current was observed for investigated structures with characteristic interface resistance RnS~10-6 Ohm cm2, 2 orders of magnitude lower, than for known experimental data.
