To use hydrogen as a clean energy source, some engineers want to pack it into a larger molecule, rather than compressing the gas into a tank. But getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such rhodium-based catalyst. The results are a step toward designing catalysts for use in hydrogen energy applications such as fuel cells.img src="http://feeds.feedburner.com/~r/sciencedaily/~4/KATqGMwjazQ" height="1" width="1"/
