1ST RESULTS ABOUT HYDROGEN LOADING BY MEANS OF PULSED ELECTROLYSIS OFY1BA2CU3O7 PELLETS

Y1Ba2Cu3O7 (YBCO) sintered pellets have been loaded at room temperatur e with hydrogen by means of electrolysis in an aqueous solution (LiOH 0.3 N) with ps current pulses. The superconducting features of loaded samples have been measured as a function of the temperature by the ac magnetic susceptibility. In some conditions the YBCO pellets exhibited an enhancement of the transition temperature up to 95.4 K without a s ignificant weakening of the superconducting grain coupling. These effe cts appear to be strongly dependent on the loading conditions.
