What is the problem with hydrogen cars?

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.

What are the disadvantages of hydrogen cars?

Disadvantages of using fuel cells in cars

• hydrogen is in the gas state at room temperature and pressure, so it is difficult to store in the car.
• fuel cells and electric motors are less durable than petrol engines and diesel engines, so they are not so long-lasting.
• fuel cells are very expensive.

How do fuel cell electric vehicles work using hydrogen?

Hydrogen is supplied to the negative or anode side of the fuel cell.

Anode catalyst activates hydrogen molecules,releasing electrons.

The electrons then travel from anode to cathode,creating an electrical current.

The hydrogen molecules responsible for releasing electrons become hydrogen ions.

What are hydrogen cars?

Hydrogen car. A hydrogen car is a vehicle that uses hydrogen as its fuel for motive power. A Hydrogen car does not have to be a car, it can be any transportation vehicle that uses hydrogen in a similar way, like an aircraft .

What is a fuel cell car?

A fuel cell vehicle ( FCV ) or fuel cell electric vehicle (FCEV) is a type of electric vehicle which uses a fuel cell, instead of a battery, or in combination with a battery or supercapacitor, to power its on-board electric motor.

What is a hydrogen electric engine?

The question is when. Hydrogen engines come in two varieties, electric engines powered directly by hydrogen fuel cells and those engines that are converted from traditional gasoline powered combustion engines and powered by compressed hydrogen.
