In a fuel cell car the only bi product is water vapor, just like trees and plants, meaning that fuel cell cars in metropolitan areas can to a small degree act just like green roof and trees to release water and cool the air helping reverse the heat island affect of big cities.
In Germany where hydrogen is being used as a storage for alternative energy, after the electricity is produced 90% to 93% is recovered as deionized water which is captured filtered again and then sold to manufactures needing ultra clean deionized water, like computerchip and DVD manufactures, since it is a bi product of electrical generation, it can be on average 40% cheaper than water that is processed three to four times to get it to that ultra clean deionized water! finally the other market is in the medical area where deionized water is required for many lab tests and as the base for interventions fluids like glucose or D5W IV fluids.
So you store your energy by taking water, splitting it, producing 99.999% pure oxygen and 99.999% pure hydrogen! both of which are sold to medical, manufacturing, transportation, electrical generation, then when your done you get 90% or more of your water back! making as we said solar, wind, biofuels , water treatment and anaerobic digesters all store able as hydrogen for cars and energy.
For the last five years more patents have been issued for fuel cell, hydrogen generation and storage than all other renewable patents combined, that in itself shows that many as we do feel hydrogen and fuel cells an important energy carrier like electricity itself.
Finally in closing six different types of fuel cells use other energy socks as fuel but because there is no combustion greatly reduce green house emissions from fossil fuels, so even non hydrogen fuel cells can save water and greatly reduce emissions.
