What is a good non conductive metal?

Question

Im looking to build a nice case and spacers for a fuel cell but the container and spacings between each plate need to be non conductive.

Answer 1

one of the passivation layer metals (titanium, tantalum, niobium....) but only after they have been anodized at a very high voltage for a long time. you'll end up with what is basicaly a ceramic coated metal.
