Hydrogen is very flammable and can easily explode. Look back the Hindenburg blimp that used hydrogen. Hydrogen burns very cleanly leaving just water vapor of a byproduct. Using Hydrogen as a fuel for cars sounds great except that you need to make it by splitting water into Hydrogen and Oxygen. That uses up as much energy as the burning of Hydrogen releases. In use as a fuel for cars, you can imagine the explosion when a hydrogen tank bursts and ignites.
One disadvantage of using a hydrogen electrode is that it requires careful handling and specialized equipment, which can be costly and complex to maintain. Additionally, the standard hydrogen electrode (SHE) can be difficult to reproduce consistently due to its sensitivity to impurities, temperature fluctuations, and pressure changes, which can affect the accuracy of measurements.
Hydrogen + fluorine ---> hydrogen fluoride
There is one atom of hydrogen in a hydrogen molecule.
There is no difference between hydrogen sulfide and hydrogen sulphide. The term "sulfide" and "sulphide" both refer to the chemical compound H2S, also known as hydrogen sulfide. The difference in spelling is simply a matter of regional or historical variation.
Yes, hydrogen can exist as a molecule. In its diatomic form, hydrogen atoms can bond together to form a molecule called molecular hydrogen (H2).
requires high pressure
It takes more energy to separate the hydrogen than we can get at the end.
Hydrogen is plentiful therefore cheep. It is also volatile if not handled properly. Comparatively, a hydrogen explosion can be close to a nuclear explosion damage wise.
he failed to explain line spectrum of elements except hydrogen.
The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs electric motors and it's only emission is water vapour. The disadvantages of using hydrogen fuel cells is that hydrogen does not occur naturally on Earth and thus is not an energy source. It takes a great deal of energy to extract Hydrogen from water. Hope this helps! :)

Advantages are very low emissions. Disadvantage is rarity of hydrogen fuel stations.
Advantages: Hydrogen gas is lighter than air, providing lift for dirigibles to fly. It is also abundant and inexpensive. Disadvantages: Hydrogen gas is highly flammable, posing a significant safety risk. This led to the famous Hindenburg disaster in 1937, highlighting the dangers of using hydrogen in dirigibles.
All these questions are asked separately many times over. Can this one be deleted?
Hydrogen Energy is currently more expensive than any other fuel source, there is also no existing infrastructure to accommodate a Hydrogen fuel cell. The process for extracting Hydrogen to be used also usually requires the use of burning fossil fuels, thus creating pollution. Then there is the fact Hydrogen is both hard to store and distribute.
renewable energy source non-poluting very safe and in-expensive large amounts can be stored up and used later
