Fault
Possible cause
Coat on the surface of the
catalyst
Incorrect connection between
solar modules and fuel cell
Light intensity too low
Fuel cell membrane is too dry
Fuel cell membrane is too wet

Remedy
The coat on the surface of the
catalyst, which increases the
initial output voltage of the fuel
cell, disappears after a few
seconds
Check connections and if
necessary correct
Increase the light intensity
Leave the fuel cell fi lled with
distilled water to stand for 30
minutes with the plugs facing
upward
Pour water out of the fuel cell
and leave the fuel cell to stand
open for a day
