3. Stack and System Component Information
Manual_FCS-C500_V1.1_EN
1. Stack
Is made up of plate-like cells with air channels to allow
the flow of air across the membrane. The membrane
facilitates the flow of Hydrogen creating the release
of electrons. Electrically conductive separator plates
between each pair of cells enable the flow of electrons.
The stack aspect is that they are all placed on top of each
other and held together by epoxy endplates.
2. H2 Supply Valve
It controls the H2 input. When the controller turns on, also
the H2 supply valve does. When system turns off, it is in
the off position for preventing hydrogen leakage.
3. H2 Purging Valve
The purging valve purges out the water and air gas
redundant in the fuel cells.
4. Short Circuit Unit
The short circuit unit can be turned on or off depending
on what application the stack is to be used in. When the
short circuit unit turns on, it can enhance performance of
the stack in applications where the stack is turned off for
prolonged periods.
5. On/Off Switch
It is the switch of the controller. Hold it for 2 seconds for
either on or off.
6. Blowers
Supply air to the fuel cells and meanwhile decrease the
temperature in the stack.
