Hi Sylvester....you might want to do some DD on HYGS, a Canadian company involved both in fuel cell applications and testing equipment. The company is trading at more-or-less breakeven, a rarity in a field where cash burn is the norm. HYGS is 27pc owned by GM, whereby Hydrogenics gave up the shares in exchange for all GM's IP in the fc sector. Revenues are increasing quite dramatically, with the latest figures citing a large backlog. Recent jv's include John Deere and NXTL. There is a website too...http:\\www.hydrogenics.com
Stock has been quite dull recently. The problem lies in the market not expecting much to come of fc's, apart from some headline-type applications, for several more years. GM doesn't expect commercial vialbility on autos, for example, until 2010, and even then dependent on solving the greatest problem: storage. Interestingly, GM also owns a chunk of Quantum, formerly part of engineering group Imco, who seem to be nearest to finding a way round the storage question. All IMHO of course.
Disclaimer: Obviously, I own some of these!
