Hydrogen fuel cell
100
Why aren't there many hydrogen fuel stations in the Caribbean?
Fuel cells are not very popular and not used widespread across the countries and they are not convenient to the Caribbean countries.
100
Name 3 advantage of the Hydrogen Fuel cell
By products are drinkable water, environmentally friendly, no pollution
100
Does the hydrogen fuel cell require fossil fuels to run?
No, only hydrogen and oxygen
200
What are the byproducts of the fuel cells? (outputs)
Heat and Water
200
what is a fear scientists have about the hydrogen fuel cell?
It is very flammable and could be dangerous in various weather conditions
200
give an example of ways this energy can/ has been used?
cars, NASA space shuttle, buses, boats, residential buildings in remote areas, motorcycles, submarines, laptops etc.
200
would companies invested in this idea make a lot of money? $$$
no not really because the materials are expensive to make the fuel cells
300
Where can the hydrogen fuel cell be made?
Anywhere with available hydrogen and oxygen, it is a great alternative to fossil fuels
300
What is one disadvantage of the Hydrogen fuel cell
Expensive,hydrogen has to produced first, storage concerns
300
What are the key components of the fuel cell process?
2 Hydrogen, Oxygen, Cathode, Anode, Membrane, Protons, Electrons
300
If fuel cells run on Hydrogen and oxygen which reagent would a company need to purchase and why can't they just use water.
A company would need to purchase the Hydrogen, they can't purchase water and use it because they need the hydrogen and oxygen to separated and in their gaseous form.
400
What is the difference between a battery and a hydrogen fuel cell?
The Chemicals are stored in the battary
400
What sort of weather will a fuel cell not work properly
extreme cold or heat
400
What kind of device is a hydrogen fuel cell?
Electrochemical divice
400
Why aren't people driving these hydrogen fuel cell cars?
-They are expensive -most people already have cars -most large vehicle corporations do not invest in fuel cell cars, and if they became popular oil companies would loose money.

Explain how the fuel cell works
A fuel cell converts chemical energy from a fuel (hydrogen) into electricity through a chemical reaction of hydrogen ions and an oxidizing agent (oxygen). The energy will flow continuously for as long as these inputs are supplied.
500
explain why fuel cells are not as used as much as fossil fuels for energy
The invention is newer and most people are used to using fossil fuels and the cost of hydrogen fuel cells is very expensive.
500
How is the fuel cell different from a battery?
Hydrogen fuel cells converts the chemical energy from a fuel into electricity through a chemical reaction of hydrogen and oxygen.
Hydrogen fuel cells require a continuous source of fuel and oxygen or air to sustain the chemical reaction.
In a battery, the chemicals present in the battery react with each other to generate an electromotive force.
500
How much does one kilowatt of energy produced by a hydrogen fuel cell cost right now, if one kilowatt produced is 10^2 + 10^2 + 200x2 + 200x2?
$1,000 initially for each kilowatt of power generated.
