Abstract
Electrolysis of D2O with Pd rod was performed under static or dynamic charging condition. The current densities were increased in steps in a long duration of electrolysis. During static charging, the Pd electrode was removed from the cell and partially outgassed in air. Resumpt ion of the charging produced several repeated heat bursts. In the dynamic test, cyclic torsion was applied to the Pd electrode during the charging. No abnormal reaction was found during the torsion, but sometimes repeated occurrance of heat burst was observed a fter the cease of torsion. Possible causes for the heat bursts are proposed .
