11. Trouble Shooting & system checks
Check the external power supply
The battery might not be operating correctly or in the case of a battery may not have any charge left.
1.
Disconnect the external power source.
2.
Using a multimeter take a reading of the positive and negative connection points on the external
power connectors to the controller.
3.
If the power is <12V (<24V in H-5000) then the power is not coming through to be able to power
the controller, blowers and valves.
4.
Change or recharge your power supply and check the voltage that it meets the fuel cell voltage
before connecting it up to the controller.
Check the SCU
1.
During operation with the SCU on, the voltage of the fuel cell will drop for 100ms every 10 secs.
2.
If the fuel cell voltage is not dropping then contact
sales@fuelcellearth.com
with the
diagnostic
“SCU not operational” with the controller number.
If the stack is un-used for a long period of time (more than 4 weeks and performance goes
down 50% to the rated power at 28.8V):
Rejuvenate by
injecting
water into
the
stack before use:
1.
Connect a short section of hosing to the gas port marked
“
H2 in
”.
2.
Fill a syringe with water (distilled or purified). Make sure there is no air in the syringe. And then
connect it to the hose attached to the
“H2 in” port.
3.
Inject distilled or purified water into the stack until you see water coming out of the
“H2 out” port.
Keep the water inside the stack for about 2 minutes. Now disconnect the syringe with the tube,
and leave the water in the stack.
4.
Purged the water out of the stack.
Connect a short tube to the "H2 out" port. And connect the H2 supply (0.45-0.55Bar) to the
stack without a load attached, to purge water out of the stack as much as possible (i.e. letting
hydrogen flow through the stack to remove water and other contaminants). Using the fuel cell
stack with too much water inside can irreparably damage it! Make sure the hydrogen supply
pressure is 0.45-0.55Bar. Please see
Storage and Re-use.
WARNING:
Please make sure you have purged the water out of the stack as much as possible before use, say,
it is not coming out of the output if you injected water into the stack. Using the fuel cell stack with
too much water inside can irreparably damage it!
