The Fuel Cell Quiz
by Staff
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:

  • 1839
  • 1915
  • 1989

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?

  • weight
  • cost
  • pollution

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.
