INTRODUCTION TO FUEL CELLS
Fuel cells have the potential to revolutionize the way we power our nation, offering cleaner, more-efficient alternatives to the combustion of gasoline and other fossil fuels. A fuel cell is a device that uses hydrogen and oxygen to create an electric current.
The amount of power production by a fuel cell depends on several factors, including fuel cell type, cell size, the temperature at which it operates, and the pressure at which the gases are supplied to the cell.
A single fuel cell produces enough electricity for only the smallest application. Therefore, to provide the power needed for most application, individual fuel cells are combined in series into a fuel cell stack. A typical fuel cell stack may of hundred of fuel cells.
A fuel cell is an electrochemical conversion device. It produces electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte. The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Fuel cells can operate virtually continuously as long as the necessary flows are maintained.
OBJECTIVES OF OUR PROJECT
Our project is entitled design and fabrication of fuel cell for power generation
There are many fuel cells of various ranges depending on the application available in the market. We take alkaline fuel cell for our project because of its simple design, low cost and effective power.
Our aim is, to produce electric power from our project from this fuel cell.
Following components and materials are used in our project.
Components used:
1) Plastic container
2) Die
3) Electrodes
Container
It is the main component used here with its technical name is stack. This stack is the housing for potassium hydroxide and electrodes. The chemical reaction place inside this stack. The external circuits are placed above the stack.
Material used: plastic.
Electrode making process
With the use of PTFE powder, graphite powder and platinum powder, electrodes are to be prepared in powder compaction press machine.
In that single stack we will get 0.7 voltages only. As many as the number of stack that much of voltage can be produced.
