PRINCIPLE OF FUEL CELL ENERGY

what is the use of fuel cell?

This heat can be used to fulfill heating needs, including (. ) and space heating

• Dirty water

• Clear water

• Cold water

• Hot water

Define fuel cell

• A fuel cell is an electrochemical

  cell that converts the chemical

  energy of a fuel (hydrogen) and

  an oxidizing agent (oxygen) into

  electricity through a pair of redox

  reactions.

• A fuel cell is an mechanical

  cell that converts the chemical

  energy of a fuel (hydrogen) and

  an oxidizing agent (oxygen) into

  electricity through a pair of redox

  reactions.

• A fuel cell is an petrochemical

  cell that converts the chemical

  energy of a fuel (hydrogen) and

  an oxidizing agent (oxygen) into

  electricity through a pair of redox

  reactions.

• A fuel cell is an Biochemical

  cell that converts the chemical

  energy of a fuel (hydrogen) and

  an oxidizing agent (oxygen) into

  electricity through a pair of redox

  reactions.

what is principle of fuel cell?

i) A typical cell running at 0.9V has an efficiency of about 90%.

ii) The only by products are water and there are virtually no pollutants.

iii) The remaining 50% will be converted into heat.

iv) The fuel cell enables hydrogen and oxygen fuel to be converted to electricity.

• i,ii&iii

• ii,iii&iv

• ii,iii&iv

• i,ii&iv

Choose 3 type of fuel cell

i. PEM

ii. SOFC

iii. FCMC

iv. DMFC

• i,ii, and iii

• i,ii and iv

• i and ii

• i and iii

which statement above is the advantages of fuel cell?

• Higher efficiency compared to IC engines

• Wide variety of production methods

• Pollution free

• No moving parts

choose one application of fuel cell.

• water

• Gas

• Portable 

•  Aeroplane

power plant Fuel Cell consists of three component. choose the correct answer

• Hydrogen storage, fuel cell stack, battery

• boiler, steam drum, and superheater.

• turbine, generator, and condenser.

• anode, cathode, and electrolyte.

Disadvantages of Fuel Cells

• More expensive than other energy sources.

• Pollution free (only emits water).

• More efficient than internal combustion engines.

• low price
