Five years ago, Leon Strecker's technology education class at Darien High School came up with the idea of building a fuel cell-powered go-kart. In previous years, the class had worked on other creations, such as electric cars that competed in a state-sponsored race and a full-size hovercraft. But students had not taken on anything anywhere near this caliber. The design was fairly simple--the team used a 1.2 kilowatt fuel cell on an old go kart, which served as a mule, or test-bed of components, for future projects. Although the fuel cell had no more power than a weed-whacker, the team that year was able to achieve speeds of 25 mph. This article discusses how technology education students at Darien High School research, design, and build the fuel cell hybrid car.
