Volkswagen, Mercedes-Benz and BMW and other auto companies are actively engaged in hydrogen vehicle research, but are taking different technological routes. laptop battery Volkswagen and DaimlerChrysler have chosen to fuel cell technology as the development direction of BMW’s hydrogen internal combustion engine technology is dedicated to research and development. By the end of 2006 the new BMW 7 Series Hydrogen internal combustion engine cars launch marks a world’s first hydrogen-driven, almost zero-emissions family car was born. The car carrying hydrogen (8kg of liquid hydrogen),  dell Latitude D820 battery and dell Latitude D830 battery with hydrogen and gasoline dual-fuel engine can switch on the dashboard to free switching, when the hydrogen fuel-driven, when, 0 ~ 100km / h acceleration time of 9.5s, the maximum speed of 230km / h. Millions of dollars with the current cost of fuel cell engine compared to the cost of hydrogen internal combustion engine has a tremendous competitive advantage.
China is still in development stage, it plans to fuel cell buses as a breakthrough in fuel cell commercialization. In 2008 during the Olympic Games, Shanghai Volkswagen launched a DMFC fuel cell vehicles,  dell C1295 battery, dell GD761 battery , a fuel charge can run 300 km.
