OVERVIEW
The principle of the fuel cell was discovered by German scientist Christian Friedrich Schonbein in .
Based on this work, the first fuel cell was demonstrated by barrister Sir William Robert Grove in the February .
Fuel cell technology was first used by NASA for use in space vehicles.
Introduction
Solid oxide fuel cells use a solid material, most commonly a ceramic material as the electrolyte.
They require high operating temperatures about 800°C to 1000°C.
They can be run on a variety of fuels including natural gas.
SOFC has Anode ,Cathode, Electrolyte
Principles of Fuel Cells:-
A fuel cell is an electrochemical device that converts the chemical energy of a reaction
between a fuel (e.g. hydrogen, natural gas, methanol, and gasoline) and an oxidant (air or
oxygen) directly into useable electricity.
A type of fuel cell in which the electrolyte is a solid, nonporous metal oxide, typically zirconium oxide (ZrO2) treated with Y2O3, and O-2 is transported from the cathode to the anode. Any CO in the reformate gas is oxidized to CO2 at the anode. Temperatures of operation are typically 800°C – 1000°C
Applications
Fuel cells are very useful as power sources in remote locations ,
spacecraft,
remote weather stations,
large parks,
communications centers,
rural locations
