Question
Solid oxide fuel cells (SOFC) are not being used in transportation application (such as automobiles and buses). What fuel cells are being used for these applications and what are their advantages over the ceramic-based SOFCs?
Explanation / Answer
(SOFC) is an electrochemical conversion device that produces electricity directly from oxidising a fuel. All fuel cells are made up of 3 parts - an electrolyte , an anode & a cathode. SOFC having ceramic electrolyte.
Fuel cells in vehicles generate electricity to power the motor , generally using oxygen from the air & compressed hydrogen. Most fuel cells emit only water & heat.
Hydrogen fuel cells are used for transportation application. It fns like a battery , producing electricity, which can
run an electric motor. Instead of recharging , fuel cell can be refilled with hydrogen.
Advantages - Have higher efficiency.
It is abundant & can be made from renewable energy.
The only by - product at pt of use is water.
