Troubleshooting
Despite hydrogen production, the load (illuminated graphic) connected to the fuel
cell is not working.
Possible cause 1:
n
The overflow is not secured firmly in place.
Solution:
n
Secure the overflow firmly in place.
Possible cause 2:
n
The connecting cables of the illuminated graphic are not properly connected.
Solution:
n
Check the connecting cables and the power source.
Possible cause 3:
n
The product requires a brief warm-up period before the hydrogen produced by the
electroly
z
er reaches the fuel cell stack, where it is converted to electrical energy. Warm-up
takes approximately 5 to10 minutes. If the model is operated by solar module, and if lighting
conditions are poor, warm-up may also take longer.
Solution:
n
Wait an appropriate amount of time (maximum 20 minutes).
The fuel cell has only a low output.
Possible cause 1:
n
The fuel cell was stored too dry or for too long. A fuel cell with a dry polymer electrolyte
membrane (PEM) will lose power.
Solution:
n
Continue operation. The fuel cell automatically moistens itself during operation, which will
slowly let it reach its full capacity again.
Possible cause 2:
n
Water has entered the fuel cell during operation. This may cause a rapid decline in performance.
Solution:
n
Continue operation. Excess water will be expelled from the fuel cell during operation.
Consequently, the fuel cell will slowly return to full capacity.
