Aluminum Alloy Releases Hydrogen From Water

Posted by kdawson on from the fill-'er-up-with-AlGal dept.

mdsolar writes "PhysOrg is reporting on a method of releasing hydrogen from water by oxidizing aluminum in an alloy with gallium. In the presence of water the aluminum oxidizes, leaving aluminum oxide, gallium, and hydrogen gas. The Purdue scientists who discovered the effect think this could help to overcome difficulties with hydrogen storage. Quoting: 'On its own, aluminum will not react with water because it forms a protective skin [of aluminum oxide] when exposed to oxygen. Adding gallium keeps the film from forming, allowing the aluminum to react with oxygen in the water.'"

    GMC sells trucks, not cars. 100% of GMC "cars" get 1000mpg, because they don't exist. Somehow I doubt GM (no C)averages better than 25mpg city for 90% of their cars. Particularly in the US.
