The only reason that car makers still invest in fuel cells is that fuel cells generate more power than batteries. However, progress is made fast in the battery world and a promising technology are ultracapacitors, which combine (some of the) energy storing capacity of traditionla batteries and the power capacity of capacitors.]]> Sun, 31 Aug 2008 00:08:36 -0400 Electric cars store the electricity directly in batteries or ultracapacitors, so you have one step less in energy coversion, which make electric cars more energy efficient.
