hydrogen fuel cells are a type of alternative energy. these cells are expensive, but they produce no air pollution. what is the major by - product of hydrogen fuel cells? water carbon dioxide

Answer

Brief Explanations:

Hydrogen fuel cells work by combining hydrogen and oxygen. The chemical reaction (2H_2 + O_2=2H_2O) occurs. Since there is no carbon involved (unlike fossil - fuel combustion which produces (CO_2)), the major by - product is water. Carbon dioxide is not produced as there is no carbon in the reactants (hydrogen fuel cells use hydrogen, usually from electrolysis or reforming without carbon - containing products in an ideal, non - fossil - based hydrogen source).

Answer:

Water
