Define hydrogen fuel cell.
Device that combines hydrogen and oxygen to produce electricity, water, and heat.
What is an anode?
The negative electrode in a fuel cell where hydrogen gas is fed.
What is a cathode?
The positive electrode in a fuel cell where oxygen from the air enters.
Define electrolyte (in fuel cell context).
A substance between the anode and cathode that allows ions to move.
What is PEM fuel cell?
Proton Exchange Membrane fuel cell; commonly used in vehicles and portable devices.
Define cogeneration.
Producing both heat and electricity.
Define fuel cell efficiency.
Measure of how much energy is converted to electricity versus wasted.
What is a byproduct?
A secondary product made in the manufacture or synthesis of something else.
Define renewable energy.
Energy that is collected from renewable resources that are naturally replenished.
What is a pollutant?
A substance or thing that pollutes something, especially water or the atmosphere.

What is cogeneration?
The simultaneous production of both heat and electricity.
Define 'fuel cell' efficiency.
The percentage of chemical energy in the fuel that is converted into usable electricity.
What is a byproduct?
A secondary product made in the manufacture or synthesis of something else.
Define 'renewable energy'.
Energy from a source that is not depleted when used, such as solar power or wind power.
Define 'emission'.
The production and discharge of something, especially gas or radiation.
