How does a fuel cell generate electricity?
Q: How does a fuel cell generate electricity?
A: A fuel cell generates electricity by mixing fuel with air and creating a reaction that releases energy, creating water and sometimes carbon dioxide.
Q: What is the most common fuel used in fuel cells?
A: The most common fuel used in fuel cells is hydrogen.
Q: How does a fuel cell differ from a battery?
A: A fuel cell differs from a battery in that it is constantly being fed with fuel so it never runs out, as long as there is enough fuel available.
Q: What is the hydrogen economy?
A: The hydrogen economy refers to the use of hydrogen as a fuel source in order to reduce dependence on fossil fuels.
Q: How is hydrogen produced?
A: Hydrogen can be produced using a process called steam reforming or extracted from water using a process called electrolysis.
Q: What happens when hydrogen is separated from fossil fuels?
A: When hydrogen is separated from fossil fuels, carbon dioxide is released.
Q: Can hydrogen be produced in a way that does not emit any harmful emissions?
A: Yes, if the energy used to produce hydrogen comes from renewable sources like solar or wind, the hydrogen produced is benign because no emissions are released. Hydrogen can also be separated from renewable biogas, which means the carbon emitted is not of fossil origin and therefore is part of the natural carbon cycle.
