DaimlerChrysler and Ford are teaming up with oil companies, a fuel-cell firm, and the state of California to build a demonstration fleet of as many as 45 fuel-cell cars and buses by 2001. The test program is seen as a big step forward in making the technology widely available. Meanwhile, GM and Toyota today will announce a five-year partnership to develop fuel-cell cars and other alternative-fuel vehicles. Many major automakers have pledged to put fuel-cell vehicles on the market by 2004.
