Mayors from around the world met at U.N. World Environment Day 2005 in San Francisco last week to create a plan for a sustainable urban future. At an opening day festival for the event, more than 60 companies showed off fuel cell-powered vehicles such as the new Honda FCX. Other carmakers showcasing fuel-efficient vehicles included Nissan, GM, DaimlerChrysler and Toyota.
Honda's fuel cell stack provides power to the compact car. It can operate at temperatures as low as 4 below zero and as high as 203 degrees.
