Yes it is yaro,
I have a friend who have a patent for the generation of h2 and 02 and it uses palladium second him, we calculated the price to construct a little device, and was around 7keuros at that time, and palladium and platinum were responsible for almost half of this value. the other half was for the rectifiers and the rest for the capacitor and pumps, magnets...
palladium have the ability of absorbing hydrogen ions. or deuterium ions...
