Checking the Fuel Cell System
-
If the fuel cell shuts down you need to check the voltage of the fuel cell by measuring between
the FC+ and FC- connectors on the fuel cell. There are 3 possible scenarios:
-
Voltage = 0
o
Check the supply valve and purge are open.
•
If not open, see Checking Valves in trouble shooting.
•
If open, check that the wire FC+ and FC- from the fuel cell controller are
connected the right way around to the fuel cell FC+ and FC- connectors, red-red and black-black.
•
If wiring wrong, change it to be correct immediately, repetitive attempts at
starting the stack with this setup will permanently damage the stack.
•
If wiring correct, disconnect the FC+ and FC- from the fuel cell controller and
start the fuel cell system again, it will shutdown automatically, following this measure the fuel cell
voltage.
•
If voltage is still = 0, the stack has short circuited internally and needs to be
changed. Contact
sales@fuelcellearth.com
with the diagnostic
“fuel cell internal short circuit” with
the fuel cell number.
•
If voltage is >0, then the controller has a problem. Contact
sales@fuelcellearth.com
with the diagnostic
“Controller internal short circuit” with the controller
number.
-
Voltage <0.6 per cell
o The fuel cell is dehydrated and needs re-hydrating. Follow the re-hydrating the fuel cell
Conditioning the fuel cell steps.
-
Voltage >0.6 per cell
o The
fuel
cell
itself
is
therefore
fine
and
the
fuel
cell
controller is reading the voltage wrong.
o Check the various connection points between the fuel cell stack and the controller are
firmly in place.
o Re-start the system. If the problem continues contact
sales@fuelcellearth.com
with
the diagnostic
“controller reading too low voltage” with the controller number.
Checking Valves
1.
With the system completely setup, Start the system.
2.
Once the system has started, you will hear a 3 seconds long purge from the purging valve,
this is the initial hydrogen going through the fuel cell to clear any non-Hydrogen gas from the system.
If you do not hear the hissing from the purge valve,
a) Check the supply valve and purge valve are opening, this is can be done by:
i. Holding the valves during the starting up and feeling the clicking motion inside the valves.
ii. Alternatively, apply the external power directly to each valve at 12V to feel and hear the
clicking of the valves opening.
iii. If either of the valves are not opening, then contact
sales@fuelcellearth.com
with the
diagnostic
“Supply valve is not opening” and/or “Purge valve is not opening” with the fuel cell number.
3.
If the valves are opening, check before starting the system again:
a)
The 8pins plug connector is firmly clicked together.
b)
The hydrogen supply:
i. Is open.
ii. Input pressure is 0.45-0.55Bar.
4.
If both valves open, system will follow normal start up procedures.
5.
If either of the valves still don’t open. Check the controller section on Valves in Trouble
shooting.
