One of the most significant technological issues of the 21st Century is finding a way to fulfill the energy demands without destroying the environment through global warming and climate change. Worldwide human population is on the rise, and with it, the demand for more energy in pursuit of a higher quality of life. In the meantime, as people use up their fossil fuel energy supplies, the quality of their environment is diminishing. By finding a way to provide clean, sustainable, environmentally friendly energy, people can reduce greenhouse gas emissions and help reverse the negative trends afflicting the planet. One very promising technology that is currently being utilized and is continually being improved is the hydrogen fuel cell (HFC). It is an energy-conversion device that converts hydrogen fuel into usable electricity. HFC technology has the potential to help satisfy the rapidly growing energy demands of the world, and in turn, improve the quality of the environment. With this kind of potential, research and development in HFC technology continues to produce viable energy alternatives through the combined efforts of many scientists, engineers, and technologists. This article provides an overview of HFC technology, and with it, a description of its simplicity in design and functionality. In addition, a rationale for HFC content and several strategies for teaching about this exciting technology are presented. (Contains 4 figures.)
