| A lot of talk has been going around in this country | | | | membrane fuel cell (PEMFC). The department of |
| about use of alternative fuels and particularly a lot has | | | | energy is concentration on this type as it has the |
| been said about the hydrogen fuel that runs on | | | | potential of being used for vehicle applications |
| hydrogen fuel cells. But do we have a clear | | | | The positive thing about PEMFC is that it has a high |
| understanding of how the hydrogen fuel cell works? | | | | power density with relatively lower operating |
| Definition can be made very simple or on other hand it | | | | temperature (ranging from sixty to eighty degrees |
| can be explained in a very complicated terminology .In | | | | Celsius or 140-176 degrees Fahrenheit) .Due to its low |
| the cell the conversion of chemicals namely oxygen | | | | operating temperature it doesn't take much time for |
