The Future of Fuel Cells
It is believed that in the future, it will be possible for car motors, batteries in electronic gadgets, and even energy stations will be replaced by fuel cells. These nifty little units are energy converters and work on the very same basic principle as do batteries. They have two electrodes which separated by electrolytes which are substances that are capable of conducting electrical current. A fuel such as hydrogen will go into one electrode while oxygen enters the other one. After they react, they collectively create an electrical current. In the case of using hydrogen, the only waste product is pure water.
There are plenty of advantages of using fuel cells. To begin with, they convert energy much more efficiently than do conventional energy sources. Whenever fuel cells are used in car engines, they are twice as efficient with no pollution at all produced. Also, they contain no moving parts which make them low maintenance in addition to being quiet. Using them in a car will greatly reduce any vibration.
Of course, fuel cells also have their problems as well. The first issue with them is that they are very costly. And because so few of them are ever made nifty live, the cost is naturally higher. It is expected that if mass quantities were produced, then the price would go down significantly. Also, because the technology is so new, the reliability of many fuel cells is not that good. One issue is that they tend to have poor power to weight ratios, meaning that they produce small amounts of power for the weight they carry.
Hopefully, as our knowledge of these devices increases, we will make them a feasible option for a reliable energy source. Not only would we benefit from the reduced cost and maintenance, our environment would benefit even more.
