Fuel cells are still pricier than even premium-grade gas -- do you know why? Test your fuel cell know-how in this quiz and learn some cool fuel cell facts along the way.
What is the difference between a battery and a fuel cell?
- A battery eventually dies, but a fuel cell continually recharges itself.
- A fuel cell can be used only in a car, while batteries have lots of uses.
- Fuel cells are cheaper than batteries.
The first fuel cell was invented by Sir William Grove in:
If you see a car running off a fuel cell, that cell is probably a:
- polymer exchange membrane fuel cell (PEMFC)
- solid oxide fuel cell
- alkaline fuel cell
What are the four main parts of a PEMFC?
- the catalyst, the battery, the cathode and the anode
- the anode, the cathode, the electrolyte and the catalyst
- the electrolyte, the catalyst, the anode and the generator
A PEMFC converts:
- hydrogen and oxygen into water
- water into hydrogen and oxygen
- hydrogen and carbon into propane
The byproducts PEMFC creates are:
- carbon dioxide and water
- heat and water
- hydrogen monoxide and water
What is one of the primary downsides of fuel cells?
The weather can be a problem for PEMFCs because:
- Their interior membrane has to stay moist for the cell to work.
- The cell will short-circuit if it gets wet.
- A PEMFC is very sensitive to minute changes in temperature.
The Hydrogen Fuel Initiative (HFI) encourages the development of hydrogen and fuel-cell technologies. This initiative was announced:
- by President Clinton in 2000
- by President Bush in 2003
- by President Bush in 2008
The U.S. government is funding fuel cell research because:
- Fuel cells are much more efficient than other power sources.
- Fuel cells can cut down on the amount of oil Americans use.
- The hydrogen infrastructure needed to support fuel cell use will be cheap to build.
