Hydrogen Fuel Cell Economy

Introduction

Let us discuss about the hydrogen fuel cell economy. The fuel cell is combined with of hydrogen and oxygen. The fuel cell to create the electricity, heat and water. The working electric power energy produced by chemical reaction in hydrogen fuel cell. The cell in which by incineration of gaseous fuel, the incineration effect obtained is changed into electrical effect in single step. Those cells are called as the hydrogen fuel cell economy.

Explanation of Hydrogen Fuel Cell Economy

 The simple explanation of cell utilizing hydrogen fuel cell economy is given in following diagram.
                               
In a vessel two porous carbon disphrams are placed and concentrated aqueous solution of NaOH is filled in between. Both these disphrams work as inert electrodes. The electrode substitute as anode consists of combined powder of platinum and silver oxide as catalyst. When hydrogen gas from the anode and oxygen gas from the cathode are passed the next reactions take place at the electrodes and electric current is formed.
            
      
 Theoretically it can be expected that the efficiency of like this cells may be 100% but in reality the efficiency is about 70-75%. The potential of this cell is about the volt is 1.23. Next we see the advantage of hydrogen fuel cell economy.

Advantages of hydrogen fuel cell economy
There are many advantages of the hydrogen fuel cell economy as compared to other cells. There is no air pollution due to this hydrogen fuel cell economy. It does not produce noise and its efficiency is especially high as compared to electrical production by thermal power station.

           The American scientists used this type of cell in space shuttle during Apollo space program. In addition the steam produced during cell reaction was cooled and used the available water. Recently, use of such hydrogen fuel cell economy is increasing in foreign countries.
