What a concept! GM has introduced the Sequel, its newest effort to produce a green car. Fueled entirely by hydrogen fuel cells, the experimental car is designed to cut emissions to nearly zero, get 300 miles to a “tank,” and drive as well as any car on the market. Engineers are even working on home storage units that would allow drivers to “fill up” in their own driveways. Sounds perfect. But it is still a concept, and there are many obstacles to making it a reality.
While hydrogen is plentiful in many different forms, the processes needed to extract enough of it to create large reserves for public use would still create a lot of pollution, defeating the purpose of turning to hydrogen. There is also no infrastructure of hydrogen stations to support fuel cell cars, and establishing one is going to be extremely costly. And speaking of cost, the Sequel is now so expensive to build that it would cost “more than a warehouse full of Corvettes,” as a reporter put it.
Why is there such a rush to make hydrogen cars feasible? Car manufacturers and the public didn’t seem too concerned as long as gas was cheap and readily available. But spiking prices, instability in the Middle East, and dire news about global warning have made it clear that alternative fuel sources must be a priority. The auto industry is also encouraged that we have embraced affordable hybrid gasoline-electric cars and are demanding a wider variety of them.

What it is. Howstuffworks.com’s How Fuel Cells Work is a thorough, comprehensible explanation of fuel cells, their pros and cons, safety issues and much more, including links to other excellent sites pertaining to fuel cell research. A complete energy and transportation education module is available at Energy Education Curriculum Project. The module addresses learning standards in science, math, language arts, and social studies.
Do it yourself. Visit National Energy Technology Laboratory’s Cool Science Teacher’s Lounge for a lesson on fuel cell technology created by middle and high school students. Simple experiments in electrolysis and ionization are included.
You auto know. GM Says Its Future is in Fuel Cells at MSNBC.com is somewhat technical for middle-schoolers, but videos, animations, and an interactive car help students visualize the technology. Kids can compare the workings of gasoline and fuel cell engines.
Cool cars. After students have researched fuel cells and their use for transportation, have them design their own fuel cell-powered car and create an advertisement for it.
Get energetic. Here are additional teaching materials and interesting sites to check out. A set of lesson plans from the New York Times Learning Network involve students in issues of fuel shortages,global warming, and politics.
Where are we going? At Energyand Cars: What Does the Future Hold?from Discovery School, students are challenged to imagine what developments will arise regarding energy technology in the next 50 years. They become archaeologists and dig up Joe’s Junkyard to reconstruct the oil-dependent society of the early 21stcentury.
Red hot hot rods. Don’t miss these two terrific Thinkquest projects. Hydrogen: An Alternative Fuel Source is not interactive, but it’s slick, sophisticated, fun to watch, and spoons out technical information in doses small enough to swallow painlessly. These are sections on fuel cell production, storage, and infrastructure. The Future of Cars is for hardcore car nuts. The clever site has some technical problems (the “Present” section has nothing in it; the “Future” photo gallery page doesn’t exist), but the “Past” section is a great history of the automobile, and the “Future” section discusses all sorts of alternative energy cars and has pictures of some really neat concept cars.
