본문내용
Chemical energy Electrical energy
Characteristic
Chemical reaction
-use oxidation
-supply fuels and oxygen from outside
-emission products to outside
Fossil fuel is limited
Fossil fuel is the main reason of global warming
The rate of energy dependence on imports is 96.8%
Increase energy import price by increasing international oil price
Tubular type
Advantage: do not need air sealing & formed on strong support ->mechanical property is great & resistance from heat is great
Disadvantage: power density is small
Economical characteristic
Do not use expansive catalyst
Do not need reforming
Do not need electrolyte supplement
Price is cheaper than others
Technical characteristic
simple process caused by various fuels
(Natural gas/coal gas)
Do not need reforming
(only for using hydrogen)
variety form and high efficiency are possible because components are solid
