Are hydrogen fuel cells dangerous?

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.

Do fuel cells combust hydrogen?

A fuel cell is a device that generates electricity through an electrochemical reaction, not combustion. In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water.

Can hydrogen explode on its own?

Even small amounts of liquid hydrogen can be explosive when combined with air, and only a small amount of energy is required to ignite it. Both its explosiveness and the extremely low temperatures involved make handling it safely a challenge.

Can a fuel cell explode like a bomb?

Hydrogen can be used to make bombs, after all. According to OSHA, “Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly. Hydrogen is a colorless, odorless, and tasteless gas.

Is it dangerous to use hydrogen in fuel cells?

Yes, hydrogen can be dangerous. There’s no doubt about it. It’s scentless and invisible, and it has the power to make things go boom. Hydrogen can be used to make bombs, after all. According to OSHA, “Hydrogen used in the fuel cells is a very flammable gas and can cause fires and explosions if it is not handled properly.

What causes an explosion in a hydrogen battery?

Sparking within the two cells next to the dead cell led first to a fire in the one (cell 2), and then an explosion in the other (cell 4). But more serious explosions can occur in older batteries where the gas-release valves fail and allow higher pressures of gas to accumulate.

Can a hydrogen car explode without an explosion?

No explosion. To have a (non nuclear) hydrogen explosion, you need a mixture of hydrogen and oxygen, ignition, and a confined space. If the mixture is too rich or too lean, nothing happens. If it is not confined, you get fire but no explosion. It is unlikely a hydrogen car will explode.
