Question 1:
Compare four different types of fuel cells and state their applications.

Aim) The main aim is Compare four different types of fuel cells and list out the applications of those fource Fuel cells.

Fuel cell :-

A fuel cell is a tiny device that has two electrodes namely, a cathode and an anode. These electrodes result in an electrochemical reaction inside the cell.

However,

A fuel cell needs to have two important components to perform this reaction. These are:

1. An oxidizing agent and
2. Supply of fuel or an electrolyte.

When these two are cut off, the cell will stop generating electric power. The electrolyte is very important because it supports the movements of ions, to and from the electrodes.

The various types of the fuel cell are as followes:-

Polymer Electrolyte Membrane(PEM) Fuel Cells:-

The Proton Exchange Membrane Fuel Cells, have an operating temperature of 50 to 100 ° C .while conducting protons. These cells consist of electrodes, bipolar plates, a polymer membrane, and a catalyst.

Solid Oxide Fuel Cells(SOFC):-

These SOFC come with a solid oxide or a ceramic electrolyte like the Yttria-stabilized Zirconia. These low-cost cells are also very efficient. However, it operates at a very high temperature. The standard operating temperature of these cells can be 600°C and 1000°C at the two extremes of the temperature scale

Alkaline Fuel Cells:-

These cells are used an aqueous alkaline solution. This solution helps to saturate the permeable milieu and helps in separating the electrodes. These cells operate at a temperature of 90 degrees Centigrade and are very efficient in producing heat and water apart from electric power.

Direct methanol fuel cell:-

The direct methanol fuel cell is a low-temperature cell, that is capable of operating with liquid methanol supplied directly to its anode. The cell uses a polymer membrane electrode, similar to that used in the proton exchange membrane fuel cell.

Camparision of Above Foure Fuel cells :-

The comparison sheet of four Fuel cells are as follows :-

Comarision sheet Link :- FCEV.xlsx

Conclusion :- The Comparision and applications for the four different types of fuel cells are explained properly.

Question 2:
Using a plot with energy density and power density on the X and Y axis, arrange various battery types like lithium ion, lead acid, Nickel Cadmium, Ultracapacitor, fuel cell.

Aim) The main aim is explain the energy density and power density for the lithium ion, lead acid, Nickel Cadmium, Ultracapacitor, fuel cell bettery types using the Plot.

The plot between energy density and power density is as followes :-

Plot--> Energy density vs Power density.

From the Graph As can be seen from the graph, lithium ion lead acid Nickel Cadmium batteries have a poor power density but a moderate energy density.

The fuel cell has a low power density and a high energy density, whereas the ultracapacitor or super capacitor has a moderate power density and a moderate energy density.

Conclusion :-All of the objectives have been met as per the requirement.
