What's fuel cell?
A fuel cell is equipment generated using the reaction of hydrogen and oxygen
Since the use efficiency of a fuel cell of energy is high, it is useful
for energy saving.
For this reason, while it is effective for global warming prevention, the
amount of discharge of sulfur oxide (SOx) or nitrogen oxide (NOx) can be
controlled, and it is environment-friendly energy.
The fuel cell starts from the experiment of the glove lord in Britain on
whether electricity being able to be made from hydrogen and oxygen in 1839
getting a hint from electroanalysis of water, and the success and the discovery.
Then, as a result of a research piling up, NASA was also adopted, and it
was carried also in the spaceship Apollo.
As for the accident of "Appllo 13" turned into a movie, the oxygen
tank for breathing and fuel cells exploded.
However, since capacity was too large for attaining general utilization,
the miniaturization was indispensable.
It became around 1986, the Ballade Power Systems Company of Canada succeeded
in the miniaturization, and the possibility of utilization increased.
And research continues being done all over the world and it has continued
up to now.
The kind and the feature of a fuel cell are as follows.
|| Reactive gas
|| Operating temperature ℃
|| Power generation efficiency %
| Polymer Electrolyte(PEFC)
|| Ion-exchange membrane
| Molten Carbonate(MCFC)
|| Zirconium oxide
|| Sodium carbonate/lithium carbonate
The following three are expectation for the use of the fuel cell.
||Home cogeneration power generation
||Business-use cogeneration power generation
||The power source for mobile
||Cogeneration is exhaust heat use of hot water by exhaust heat generated
when it power generation with a fuel cell.
