  2. Water fuel cell - Wikipedia

    en.wikipedia.org/wiki/Water_fuel_cell

    The water fuel cell is a non-functional design for a " perpetual motion machine" created by Stanley Allen Meyer (August 24, 1940 – March 20, 1998). Meyer claimed that a car retrofitted with the device could use water as fuel instead of gasoline. Meyer's claims about his "Water Fuel Cell" and the car that it powered were found to be fraudulent ...

  3. Water-fuelled car - Wikipedia

    en.wikipedia.org/wiki/Water-fuelled_car

    A water-fuelled car is an automobile that hypothetically derives its energy directly from water. Water-fuelled cars have been the subject of numerous international patents, newspaper and popular science magazine articles, local television news coverage, and websites. The claims for these devices have been found to be pseudoscience and some were ...

  4. Fuel cell - Wikipedia

    en.wikipedia.org/wiki/Fuel_cell

    Fuel cell. Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure. Scheme of a proton-conducting fuel cell. A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) [1] into electricity through a pair of redox reactions. [2]

  5. Water power engine - Wikipedia

    en.wikipedia.org/wiki/Water_power_engine

    Water fuel-cell capacitor . As the prices for gasoline continued to soar a man of many inventions named Stanley Myer worked on a solution that would cut the cost of fueling our cars as well as help the planet. The war on the supply and demand of a necessity for vehicles would become a distant memory if Myer could make his invention work for all ...

  6. Electrolysis of water - Wikipedia

    en.wikipedia.org/wiki/Electrolysis_of_water

    Electrolysis of water is using electricity to split water into oxygen (O. 2) and hydrogen (H. 2) gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or 'gas bottles', hydrogen can be ...

  7. Galvanic cell - Wikipedia

    en.wikipedia.org/wiki/Galvanic_cell

    Galvanic cell. Galvanic cell with no cation flow. A galvanic cell or voltaic cell, named after the scientists Luigi Galvani and Alessandro Volta, respectively, is an electrochemical cell in which an electric current is generated from spontaneous oxidation–reduction reactions. A common apparatus generally consists of two different metals, each ...

  8. Alkaline fuel cell - Wikipedia

    en.wikipedia.org/wiki/Alkaline_fuel_cell

    The alkaline fuel cell (AFC), also known as the Bacon fuel cell after its British inventor, Francis Thomas Bacon, is one of the most developed fuel cell technologies. Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%.

  9. Alkaline anion-exchange membrane fuel cell - Wikipedia

    en.wikipedia.org/wiki/Alkaline_anion-exchange...

    The alkaline fuel cell used by NASA in 1960s for Apollo and Space Shuttle program generated electricity at nearly 70% efficiency using aqueous solution of KOH as an electrolyte. In that situation, CO 2 coming in through oxidant air stream and generated as by product from oxidation of methanol, if methanol is the fuel, reacts with electrolyte ...
