10. Storage and Re-Use
When finished operating the stack, place it in an enclosed area for storage to keep the stack from getting
too dry. The stack should be stored at room temperature.
If the stack is un-used for a long period of time (more than 4 weeks) and it's performance goes down 50%
to the rated power at 28.8V after 30 minutes operation, we recommend do the following steps.
Note: Generally, injecting water into the stack it is not recommended. Only if the performance of the stack
decreases 50% is it recommended to inject water into the stack to activate the stack before operation.
Rejuvenate by injecting water into the stack:
1. Connect a short section of hosing to the
gas port marked “
H2 in
”.
2. Fill a syringe (not provided) 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 s
ee water coming out of the “H2 out” port
(see picture A below only for reference). 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 as much as possible before use, say, it is not coming out of the
output. 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! Please see picture B below only for
reference.
Make sure the hydrogen supply pressure is 0.45-0.55Bar.

WARNING:
1. 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!
2. The tube between the hydrogen pressure regulator and the fuel cell gas input is required to be less than
30cm.
3. The stack must be standing on the clear plastic feet.
