Plug Power, Plug Power, Plug Power. This will be one of the biggest players of Fuel Cells for Industrial lift trucks. Plug Power recently bought out Cellex which make the smaller 24 volt fuel cells for pallet moving trucks. Plug Power announced on 4/18/2007 that it is in the process of buying out General Hydrogen. General Hydrogen presently makes 36 and 48 volt fuel cells for the stand-up/reach trucks and the sit-down (hyster style) lift trucks. This will complete the class 1, 2 and 3 fuel cells. This will make them the leader in the United States. The only other company that may have a product out soon could be Deka/Nuvera. They are presently trying to perfect the class 2 (36v) fuel cell which is still being tested at the Deka battery plant. The General Hydrogen fuel cell power packs are presenty being used in the hundreds through-out the United States with little to no problems. The Price however is still a problem. The traditional batteries are cheaper to operate at this time but the pendulum is rapidly swinging to the fuel cells favor.
