Terminology
PEM fuel cell:
A PEM (Proton Exchange Membrane) fuel cell is a device that converts hydrogen
and oxygen into water and electricity.
A fuel cell stack:
It includes a plurality of plate-like fuel cells arranged along an axis generally
parallel to cell thickness with electrically conductive separator plates between
each pair of cells.
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:
A process to humidify the proton exchange membranes for optimal performance.
Blower:
Fans attached to fuel cell stack to supply cooling air and process air.
Purging valve:
Excess water and hydrogen will be dispelled from the fuel cell flow channels via
purge valve.
SCU:
Short circuit unit – the short circuit will be controlled for good performance of the
stack.
Mass flow per minute:
The amount of hydrogen consumed to run the fuel cell at a certain power.
HFCT:

Blower controller:
When no load is connected, turn off the blower controller to reduce the power consumption
of the stack.
