Possible cause:
■
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:
■
Continue operation. The fuel cell moistens itself during operation, which slowly allows it
to reach its full capacity again.
Despite hydrogen being present, the load connected to the fuel cell (e.g. the motor) is
not working.
Possible cause:
■
Water has entered the fuel cell during operation (e.g. through the gas storage tanks). This
may cause a rapid decline in performance.
Solution:
■
Dry the fuel cell by opening and blowing out the connections.
CAUTION
Risk of damage due to compressed air
The use of compressed air for drying the fuel cell may cause
irreparable damage to the fuel cell.
When drying it, only blow out the fuel cell without using any
high pressure air
.
With the solar module connected, no hydrogen is produced in the
electrolyzer
Possible cause:
■
The light intensity is insuffi cient.
Solution:
■
Operate the solar module(s) using either adequate direct sunlight or concentrated light
from a powerful electrical light source. Energy-saving light bulbs, fl uorescent tubes etc.
are unsuitable for the operation of solar modules.
Troubleshooting
The fuel cell only has a low output.
