Performance of Hybrid power source
Conclusion : Hybrid System
Q & A
fuel cell is a kind of generator that provides electricity, batteries are like warehouses that store electricity.
features2.
The maximum output energy from the battery
= 50% forms of energy+50% heat
=>The energy efficiency is 50%.
features3.
large energy density.
(store a lot of energy per weight)
Recently, as the amount of storage for capacitors rose, higher level of electricity application became possible to realize.
(ex) Uninterruptible(UPS), Hybrid automobile
supercapacitors have a lot in common with batteries, but we can say that they are the newest form of battery.
You can charge it in a very short period of time and repeat a number of charge and discharge periods.
The energy efficiency is much higher than a battery.
