General informationGeneral information

• The word “hydrogen“ – from Greek “water generator“

• discovered in 1766 by Henry Cavendish

• The Element no.1 in universe, biogenic

• Forms weak bonds with electronegative elements

IsotopesIsotopes

• 1H – protium – no neutron, “light H“

• 2H – deuterium – 1 neutron, “heavy H“

• 3H – tritium – 2 neutrons, “super heavy H“

ApplianceAppliance

• Reducing agent

• Welding – in mixture with oxygen

• Nuclear fusion – still in research, termonuclear bomb

• Power supply – future in energetics and transport

Welding - svařování

WaterWater

• The most common substance on Earth, but in rivers and lakes there is only less than 0,003%

• Thanks to hydrogen bonds it has annomal properties

• Tomatoes and cucumbers contain 98% water.

CompoundsCompounds

• Water

• Ammonia

• Hydrides

• Acids

• Organic compounds

• Hydrogen peroxide

Hydrogen – future of transportHydrogen – future of transport

• Ecologic way of car gear

• In research because of strong reactivity

• 2 ways :hydrogen tank or small electrolyser in car

• Now still too dangerous and expensive

Gear - pohon
