Which of the following statements best describes the differences between hydrogen fuel cells and hydrogen fusion?
Which of the following statements best describes the difference between hydrogen fuel cells and hydrogen fusion? The correct answer is option A. “More energy is produced per reaction in a fusion reaction than in a fuel cell” .
What is the difference between fuel cell and hydrogen?
In a fuel cell vehicle, the hydrogen fuel is combined with oxygen . While the combustion in a hydrogen- or gasoline-powered engine is converted into mechanical energy, in a fuel cell vehicle, the chemical energy from the hydrogen and oxygen is converted into electrical energy.
What is a hydrogen fuel cell quizlet?
A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water . ... A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power. You just studied 10 terms!
What is hydrogen fuel cell?
A hydrogen fuel cell is an electrochemical power generator that combines hydrogen and oxygen to produce electricity , with water and heat as by-products. Simply put, hydrogen fuel cells form energy that can be used to power anything from commercial vehicles to drones.
Which of the following is the main energy source for our sun?
The sun generates energy from a process called nuclear fusion . During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.
Why are hydrogen engines a bad idea?
Hydrogen fuel cells have bad theoretical and practical efficiency . Hydrogen storage is inefficient , energetically, volumetrically and with respect to weight. ... It has a horrible well-to-wheel efficiency as a result. Easy ways to get large quantities of hydrogen are not ‘cleaner' than gasoline.
What are the disadvantages of hydrogen fuel cells?
- Hydrogen Extraction. ...
- Investment is Required. ...
- Cost of Raw Materials. ...
- Regulatory Issues. ...
- Overall Cost. ...
- Hydrogen Storage. ...
- Infrastructure. ...
- Highly Flammable.
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.
What is an advantage of hydrogen fuel quizlet?
Hydrogen-rich fuel cells produce less CO2 than hydrocarbon fuels. Hydrocarbon fuels may undergo incomplete combustion producing toxic carbon monoxide. Hydrogen fuel cell vehicles are more efficient (40-60% efficient) as hydrocarbon fuels (20% efficient) waste chemical energy though heat loss.
What waste products is are released by hydrogen fuel cell vehicles?
It is supposed to be a safe and clean alternative to burning fossil fuels to power, amongst other things, our cars, since its waste products, rather than huge amounts of carbon dioxide and even sulfur particles, the hydrogen fuel cell releases carbon dioxide in smaller amounts and water.
What do hydrogen fuel cells need to work quizlet?
Fuel cells have three layers, an anode, cathode and an electrolyte layer. When hydrogen rich fuels enter a fuel cell, it reacts electrochemically with oxygen to produce water, heat and electric power . Hydrogen fuel is produced in a process called electrolysis. ... Electrolysis is performed using fossil fuels.
Are hydrogen cars better than electric?
The main advantage of hydrogen cars is that they produce no emissions at the tailpipe – just water. This benefit is the same as with a normal electric car, and puts both at the forefront of emission-cutting tech in the automotive world.
How long does 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.
Is hydrogen fuel cheaper than gasoline?
While hydrogen is a cheaper fuel than gasoline on paper , the reality is, as of 2010, it is much more expensive. The few models of hydrogen-fueled cars that are commercially available generally cost more than $100,000. ... Thus, fueling stations are limited, making the cost of hydrogen fuel vary widely.
What are the 5 sources of energy?
- Solar Energy. The primary source of energy is the sun. ...
- Wind Energy. Wind power is becoming more and more common. ...
- Geothermal Energy. Source: Canva. ...
- Hydrogen Energy. ...
- Tidal Energy. ...
- Wave Energy. ...
- Hydroelectric Energy. ...
- Biomass Energy.
