Fleischmann and Pons believed that they had stumbled on another way - intense pressures provided by the natural make-up of solid palladium. That was offset in part by higher prices for platinum, palladium and nickel. The palladium cathode was charged with dissolved hydrogen. The electrical voltage forced the hydrogen into the palladium. Three different palladium rods were tried of various diameters: the thickest rod gave by far the greatest effect. Undoubtedly, the bubbling oxygen would have come into contact with palladium. a soft silver-white metal that is often combined with gold and silver, and used to cover an object with a very thin layer of metal.
