2. Terminology

PEM fuel cell:

a PEM (Proton Exchange Membrane) fuel cell is a device that

converts hydrogen and oxygen into water and electricity.

Reactants:

reactant is a material used to start a chemical reaction. In the fuel

cell the reactants are air and hydrogen by which the electricity will be generated.

Humidification:

humidity that the fuel cells need for running.

Blower:

supply air to the fuel cells and meanwhile decrease the temperature in

the stack.

Mass flow per minute:

the total amount of the hydrogen flow to the fuel cell

every minute

，

which the hydrogen supply can be calculated.

HFCT:
