  2. Direct-ethanol fuel cell - Wikipedia

    en.wikipedia.org/wiki/Direct-ethanol_fuel_cell

    The charge is carried by the hydrogen ion . The liquid ethanol (C 2 H 5 OH) is oxidized at the anode in the presence of water, generating CO 2, hydrogen ions and electrons. Hydrogen ions travel through the electrolyte. They react at the cathode with oxygen from the air and the electrons from the external circuit forming water.

  3. Membraneless Fuel Cells - Wikipedia

    en.wikipedia.org/wiki/Membraneless_Fuel_Cells

    Although hydrogen and oxygen are very common reactants, a plethora of other reactants exist and have been proven effective. Hydrogen for fuel cells can be produced in many ways. The most common method in the United States (95% of production) is via Gas reforming , specifically using methane, [ 2 ] which produces hydrogen from fossil fuels by ...

  4. Alcohol fuel - Wikipedia

    en.wikipedia.org/wiki/Alcohol_fuel

    Methanol and ethanol are incompatible with some polymers. The alcohol reacts with the polymers causing swelling, and over time oxygen breaks down the carbon-carbon bonds in the polymer causing a reduction in tensile strength. For the past few decades though, most cars have been designed to tolerate up to 10% ethanol (E10) without problem.

  5. Liquid rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_propellant

    Using liquid methane and liquid oxygen as propellants is sometimes called methalox propulsion. [19] Liquid methane has a lower specific impulse than liquid hydrogen, but is easier to store due to its higher boiling point and density, as well as its lack of hydrogen embrittlement. It also leaves less residue in the engines compared to kerosene ...

  6. Methanol fuel - Wikipedia

    en.wikipedia.org/wiki/Methanol_fuel

    Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline. Methanol is safer for the environment than gasoline, is an anti-freeze agent, prevents dirt and grime buildup within the engine, has a higher ignition temperature and can withstand ...

  7. Liquid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Liquid-propellant_rocket

    Bipropellant liquid rockets use a liquid fuel such as liquid hydrogen or RP-1, and a liquid oxidizer such as liquid oxygen. The engine may be a cryogenic rocket engine , where the fuel and oxidizer, such as hydrogen and oxygen, are gases which have been liquefied at very low temperatures.

  8. Liquid fuel - Wikipedia

    en.wikipedia.org/wiki/Liquid_fuel

    A flaming cocktail works by burning ethanol (grain alcohol), a type of liquid fuel also found in all alcoholic drinks. Liquid fuels are combustible or energy-generating molecules that can be harnessed to create mechanical energy, usually producing kinetic energy; they also must take the shape of their container. It is the fumes of liquid fuels ...

  9. Butanol fuel - Wikipedia

    en.wikipedia.org/wiki/Butanol_fuel

    The fuel in an engine has to be vaporized before it will burn. Insufficient vaporization is a known problem with alcohol fuels during cold starts in cold weather. As the heat of vaporization of butanol is less than half of that of ethanol, an engine running on butanol should be easier to start in cold weather than one running on ethanol or ...
