1. Hydrogen is highly flammable. This can be very dangerous if hydrogen is used as a domestic fuel or in vehicles because it can combust instantaneously.
2. Hydrogen is a gas at room temperature. This makes the storage and transportation of hydrogen more difficult as compared to liquid fuels like petrol and liquified petroleum gas, because a gas fuel occupies a large volume (unless pressuried), cannot be poured and can be easily lost to the surrounding air by diffusion.
hydrogen is highly combustible..hence direct contact can cause an immediate fibre
Much electricity is needed to generate the Hydrogen.
It is very difficult to store because it has very low density.
It is highly flammable ( more higher than gasoline).
It is not easy to set up a hydrogen fuel generating unit.
thats it even petrol and gasoline has more advantages than this and dont just see the dis advantage parts see the advantages it has.
scarcity of hydrogen..
What else can I help you with?
Is hydrogen compression possible?
Yes, hydrogen compression is possible and commonly used to store and transport hydrogen gas at high pressure. This is typically done using compressors that increase the pressure of the hydrogen gas, allowing it to be stored in pressurized tanks for various applications such as fuel cells or industrial processes.
Can you use hydrogen peroxyde in a fuel cell?
Hydrogen peroxide can be used in certain types of fuel cells called direct borohydride fuel cells. In these fuel cells, hydrogen peroxide is used as an oxidant in place of oxygen. However, the efficiency and practicality of using hydrogen peroxide in fuel cells is still being researched and developed.
What are the reactants in fuel cell?
The reactants in a fuel cell are typically hydrogen and oxygen. The hydrogen is usually supplied as a fuel source to the anode, while oxygen is supplied to the cathode.
What do hydrogen fuel cells burn with?
Hydrogen fuel cells combine hydrogen with oxygen from the air to produce electricity, heat, and water as byproducts. This process is known as electrochemical conversion.
How do you put hydrogen in a fuel cell?
Hydrogen is typically stored in a compressed or liquid form and then fed into a fuel cell. The hydrogen reacts with the electrolyte in the fuel cell to produce electricity, water, and heat. The process is efficient and does not produce harmful emissions.
What are the disadvantages of using water as a hydrogen fuel source?
It takes more energy to separate the hydrogen than we can get at the end.
What are the advantages and the disadvantages of a hydrogen fuel cell car over a hybrid car?
Advantages are very low emissions. Disadvantage is rarity of hydrogen fuel stations.
What are some advantages and disadvantages of hydrogen fuel cells?
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! :)

Is it possible to get hydrogen fuel from biomass?
Yes. However, it is not yet economically practical, as it takes more energy to convert the biomass into hydrogen than we can get from using the hydrogen for fuel.
What are the advantages and disadvantages of hydrogen as an alternative fuel?
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.
How can one get as much hydrogen as possible into a space shuttle's fuel tank?
Fill it
Can you use sucrose as hydrogen fuel in the car?
I suppose that is not possible; and also is not economic.
Is any disadvantages of fuel energizer?
yes there is no answer for disadvantages of fuel energizer
What are the disadvantages about hydrogen?
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.

What is the byproduct of hydrogen fuel cell?
Water is the benefit of a hydrogen fuel cell ;)
