Which elements do hydrogen fuel cells combine to produce electricity?
In its simplest form, a hydrogen fuel cell creates electricity by combining hydrogen gas and oxygen to form water. The electricity is then used to power electric motors or is stored in batteries for later use.
Which elements do hydrogen fuel cells combine to produce electricity hydrogen and oxygen hydrogen and carbon hydrogen oxygen and nitrogen hydrogen carbon and nitrogen?
I think the correct answer would be the first option. The elements that hydrogen fuel cells need to produce electricity are oxygen and hydrogen. The hydrogen is broken into protons and electrons with the aid of a catalyst which them reacts with oxygen producing water, heat and electricity.
How do hydrogen fuel cells produce electricity?
Fuel cells work like batteries, but they do not run down or need recharging. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity.
What types of energy are produced by a fuel cell?
Electrical energy
What are the disadvantages of fuel cells?
Disadvantages of using fuel cells in cars These include: 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 much hydrogen is needed for a fuel cell?
It would take about 10 Nm3 of hydrogen gas to equal the energy present in 1 gallon of gasoline or 8.3 pounds of coal.
What are the disadvantages of hydrogen fuel cells?
What are the Disadvantages of Hydrogen Fuel Cells?
- Hydrogen Extraction.
- Investment is Required.
- Cost of Raw Materials.

Why hydrogen is not used as a fuel?
Hydrogen has the highest calorific value so it can be considered as the best fuel but it is highly inflammable so it is diificult to store, transport and handle so it is used as a fuel only where it is absolutely necessary.
How long will a hydrogen fuel cell last?
The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.
Why are hydrogen cars better than electric?
However, as hydrogen cars densely pack their energy storage, they’re usually able to achieve longer distances. While most fully electric vehicles can travel between 100-200 miles on a single charge, hydrogen ones can get to 300 miles, according to AutomotiveTechnologies.
Does Tesla use hydrogen fuel cells?
Battery electric vehicles, or BEVs, are the electric vehicles that most of us are familiar with today, like Teslas. Fuel-cell vehicles don’t require charging at all. The hydrogen tank is refilled at a hydrogen station in less than five minutes, just like your typical gas station today.
Why does Elon Musk not like hydrogen fuel cells?
Musk HATES the idea of using hydrogen energy to power vehicles. He’s called them “fool cells.” And says using them to power vehicles is “mind-bogglingly stupid.” His basic objection is that using hydrogen to store energy can never be as efficient as storing electricity in a battery.
Does Amazon use hydrogen fuel cells?
In 2017, Plug Power and Amazon signed an agreement to utilize fuel cells and hydrogen technology in Amazon’s fulfillment sites.
