With global warming, general pollution and rising fuel prices, our future energy needs are a hot topic. Fuel cells may represent a solution, one coming sooner than later.
Future Energy Concepts The Fuel Cell
A fuel cell is a fairly vague phrase thrown around by those in the know and those that know relatively little. Regardless of the particular design, a fuel cell is essentially a cell similar to a battery in which a chemical process occurs to produce electricity. In this case, however, the fuel is hydrogen. The basic idea is to combine hydrogen with oxygen in a process that produces electricity. This electricity is then used as we would normally use it in our lives.
If you read the paper or watch the news, one would think the concept of hydrogen fuels in a new one. In fact, it is not. The first one was created in 1839. The problem, of course, was it was inefficient and there wasnt much interest since fossil fuels were plentiful and our energy needs were tiny compared to today. It wasnt until the 1960s that much interest was shown in the energy platform. As with many advances, NASA decided to use fuel cells to power the Gemini and Apollo spacecrafts....
