Cell generates electricity

We have encountered many applications in mobile technology. Blue tooth, GPRS, recently GPS have also been included. Now we are in the verge of generating electricity via cells. We can extract energy from the chemical reaction when hydrogen combines with oxygen to from water. This eminent technology is more prevalent in futuristic cars. This car inculcates tanks of hydrogen instead of gasoline, whose combustion is a key perpetrator in pollution and global warming. Developers express the fact that this process produce one-third less of the pollution that causes global warming than conventional electricity generation does. This is a plain grey cell and it resembles a suitcase in size and it is kept near the tank that turns out to be a water heater. In the course of generating electricity, the fuel cell emanates warmth to heat water for the home. The oxygen that the cell uses is derived from the atmosphere. The hydrogen is extracted from natural gas by a device called a reformer in the same box as the fuel cell. Immense drawback is that the byproduct of this process is a poisonous gas called carbon monoxide. To overcome this problem another machine is attached to the grey box that adds oxygen to the carbon monoxide to create carbon dioxide. Although it may contribute to global warming it is not a poisonous gas.
