Hydrogen itself does not generate electricity, but it can be used to generate electricity in at least two ways. First, as a combustible substance, hydrogen could be used as a fuel source for an electric generator. This process is not the most efficient means to produce electricity with hydrogen, because the conversion of mechanical energy to electricity always results in a (typically) pretty significant loss of power.
The most common social association of hydrogen and producing power these days involves a fuel cell, where hydrogen is the fuel, and the air provides the oxidant (oxygen). A fuel cell sparks a reaction between the hydrogen and the oxidant by means of a catalyst (usually a pricey metal like platinum), and electricity is produced. About half of the energy potential is lost as heat, so this process is about 50% efficient.
Interesting side note. Diesel generators can be up to 45% efficient (possibly as high as 55%). I have no idea if a hydrogen generator could be nearly as efficient burning just hydrogen. My instinct is definitely no, based only on the assumption that diesel's high efficiency comes from the high compression design as compared to a gas generator. But... it would be interesting to know if it would be physically possible to make an electric generator that burns hydrogen as efficient or more efficient than the current crop of fuel cells ;-D.
A fuel cell creates Electricity from Hydrogen and Oxygen.
Combining hydrogen and oxygen produce energy that can be transform in to electricity.
Burning hydrogen releases energy and forms water. Anytime hydrogen combines with oxygen there is energy given off and H2O (water) is formed.
A process called electrolysis.
Yes, you can turn water into oxygen and hydrogen gas with electricity; this process is called electrolysis.
Hydrogen is the most abundant element in the universe, and the third-most common element on the Earth's surface. It can be produced, among other ways, by splitting water molecules (which as a side-effect, also produces oxygen gas) in a process known as water electrolysis; by exposing metals to certain acids; or by breaking down hydrocarbons, including those found in urine or natural gas.
Oxygen and hydrogen are the two ellements that make up water.
No. It is a compound made of the elements oxygen and hydrogen: H2O.
The chemical reaction between hydrogen and oxygen produces water.
Splitting water results in oxygen and hydrogen. The water element is separated into two hydrogen atoms and one oxygen atom.
splitting of water molecule into hydrogen and oxygen.
A chemical reaction.
No. It is endothermic as it requires energy.
no, it is chemical.
The reaction between oxygen and hydrogen produce water.
Water on electrolysis (splitting) gives elements Hydrogen and oxygen in a fixed proportion
It produces Oxygen, which is criticial to life for animals
This is the word equation for the electrolysis of water; splitting it apart into its component elements.
The product is water vapor.
Photosynthesis produces oxygen gas (O2) as a by-product. The oxygen comes from the splitting of water molecules at Photosystem II.
A fuel cells uses hydrogen and oxygen to make electricity, and produces water as a byproduct.
