Plug Power adds to gains as Japan reveals fuel cell vehicle subsidies

• Plug Power (NASDAQ:PLUG) finished 10% higher on the session, apparently boosted late by Japan Prime Minister Abe's plan to provide at least ¥2M (~$19,550) in subsidies for every purchase of a fuel cell vehicle.
• The environmentally friendly cars are more expensive than conventional autos - Toyota's (NYSE:TM) model will cost ~¥7M - which led Abe to decide government support was necessary to encourage buyers.
• Earlier: Plug Power +3% after Roth Capital says outlook has improved.
