Fuel cells may seem like a science fiction fantasy to many people, since they are an efficient and nonpolluting power source producing little noise and having no moving parts. But this futuristic energy source not only exists, it has played a key role in providing electricity on spacecraft since the 1960s. Currently, technologists are developing and adapting fuel cell technology for practical use in exhaust-free automobiles and in electricity-generating plants. In this article, the author discusses the possible applications, societal impacts, and safety concerns of fuel cell technology. He asserts that it is critical to incorporate fuel cell education in the technology education classroom in order to encourage its adoption. (Contains 1 figure.)
