What produces oxygen by splitting water into hydrogen and oxygen?

Answer 1

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.

Answer 2

A fuel cell creates Electricity from Hydrogen and Oxygen.

Answer 3

Combining hydrogen and oxygen produce energy that can be transform in to electricity.

Answer 4

Burning hydrogen releases energy and forms water. Anytime hydrogen combines with oxygen there is energy given off and H2O (water) is formed.

Answer 5

A process called electrolysis.
