Study of deuterium charging behaviour in palladium and palladium alloy plates, changing surface treatments. by ms pulsed electrolysis

A systematic study about deuterium loading in palladium has been performed. A systematic study about deuterium loading in palladium has been performed. Palladium cold worked plates and palladium alloy plates have been used as comparison. A proper plate surface oxidation has been performed and anomalous absorption rates have been measured. A high peak current (15 A), short width pulse (duration 1{mu}s) electrolysis technique has been used to test all chatode plates and it is visible that this technique permits to reach very high D/Pd loading values (around 1/1 or even more for palladium). At the beginning of the loading, in close relation with the anomalous absorption rate, a bump of excess heat has been measured in two similar oxidized surface palladium plates. All these tests show that the loading is completely reproducible.
