Is aluminium metal good for absorb hydrogen? I also wonder which metals how is bad to absorb hydrogen? Its not but to find good materials for hydrogen loading but also to avoid de-loading. For example a connecting cord to an anode can de-lode hydrogen from Ni or Pd in an electrolytic experiment. It may take H/D from the anode out to the air. Even Cu may absorb some hydrogen. A "simple" thing as make a bad connecting for an anode may ruin a potential good experiment. What is good to use as connecting metal and for solder?
