A new era in the history of energy sources is called fuel cell technology. The first fuel cell was built in 1839 by Sir William Grove, a Welsh judge and gentleman scientist. ... Serious interest in the fuel cell as a practical generator did not begin until the 1960’s, when the U. ... space program chose fuel cells over riskier nuclear power and more expensive solar energy. ... The fuel cell was much more efficient for them. ... Scientists were able to use the heat from the fuel cells to actually heat the shuttle and the water which the astronauts used to bathe.
The concept behind fuel cells is actually very easy to understand. ... com, A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into electricity and heat. ... Instead of recharging using electricity, however, a fuel cell uses hydrogen and oxygen. The fuel cell will most likely compete with many other types of energy conversion devices, including the gas turbine in power plants, the gasoline engine, and the battery. Combustion engines like the turbine and the gasoline engine burn fuel and use pressure created by the expansion of the gases to do mechanical work. ...
A fuel cell provides a DC voltage that can be used to power motors, lights or any number of electrical appliances.
