Hi,
I am working on seperation chemsitry of platinum noble metals, namely
Pd, Rh, Ru. I learn that these metals are of wide interest in fuel
cells, etc due to their hydrogen stroage capacity. I have some queries
regarding this.

Does anyone working on using these metals for hydrogen storage and
energy?

A storage medium (not very good storage at that) is not what very expensive Au, Pt, etc., are good for. LaNi5 (lanthanum nickel five) is a good absorber of H2 but still expensive.

The best hydrogen storage media are heptane and iso-octane.

Nothing else comes remotely close for storage density.
Nor is anything ever likely to.


Don, what about the C load in that storage container? How do you combust only the H in the CxHy compound? The water cycle will take care of the heavier load of the H2O in the atmosphere. But (and I don't believe that CO2 is the main cause of the global warming) how do you avoid producing too much additional CO2 if you want to use H as a fuel?
