    All of the waste on or after petroleum cells be able to exit recycled and the electrochemical processes can classically be wrong way up via electrolysis, which can be mechanical starting renewable source
    Hydrogen Fuel Cells

    Hydrogen have the main energy-to-weight proportion of serval oil Its short mass seeing either pressurized gas or a liquid resource with the intention of huge volume be necessary in the direction of take the power corresponding of conformist fuel. This bonus the suppression harms require grave tank lift up challenge meant for the transportable utilize of hydrogen fuel cells. The lofty organization of fuel cells does not draw close up to manufacture out of bed for the difference in storage volumes. Even at 350 bar force it requires 11 time the size of hydrogen than that of gasoline for the equivalent energy, and (including containment) eight times the weight. Even liquid hydrogen requires four times the volume and three times the weight, and liquefaction can cost as much as a 40 percent energy penalty.

    Alternative storage methods, such as chemical binding in hydrides or sorption in nano-tubes, continue to be researched, with no clear solutions yet fully demonstrated. The alternative to carrying a fossil fuel for onboard production of hydrogen solves none of the environmental issues. However, onboard hydrogen production from other chemical reactions or biofuels remains possible. For example, Millennium Cell's Hydrogen on Demand system generates pure hydrogen from sodium borohydride. Dissolved in water and passed through a proprietary catalyst chamber, sodium borohydride releases pure hydrogen on demand. (Borohydride comes from sodium borate, commonly known as borax, which is found in substantial natural reserves globally.)

    Hydrogen fuel cell types can be classified by their operating temperatures as either moderate or high temperature. Moderate-temperature fuel cells include alkaline, proton exchange membrane (PEM), polymer electrolyte, direct methanol (related to PEM), and solid acid fuel cell. High-temperature fuel cells include phosphoric acid, molten carbonate (sometimes called direct fuel cells), and solid oxide. Each has certain advantages and disadvantages (e.g., PEM cells have been harnessed for transportation because of ease in rapid start-up and load following, whereas solid oxide fuel cells require long start-up times but are much more tolerant of fuel impurities).
    Of the many potential types of fuel cells, zinc-air (ZAFC) technologies show particular promise and are being rapidly commercialized. ZAFCs use the electro potential between zinc and oxygen, which provides theoretical efficiency limits higher than for hydrogen/oxygen and has electrochemical reversibility. Zinc carries a unique set of properties that provide advantages over hydrogen. These include high volumetric energy density, high specific energy, good conductivity, abundance, low cost, low toxicity, and ease of handling (especially compared with hydrogen).
