A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.

Each person has a share of resposability concerning the pollution of the ground, and this also applies for the air pollution (industries, vehicles, fires, toxic products ...).
According to NASA researchers, climate hazards could have an unexpected origin, that of air pollution generated by the Asian continent (seat of the majority of the global industry in several areas). These NASA scientists have demonstrated that the gases produced by the 20 most polluted Asian cities in the world affect global climate.
