00002: WHOLE SYSTEME TEST

Step	Step Description	Expected Result	Result
Precondition	System is off
Open the valves V₁ and V₂	Open the valves V₁ and V₂ from the GUI	The valve V₁ and V₂ are open and enable to let the nitrogen gas pass	Positive
WASH THE SYSTEM WITH NITROGEN	Wash the system with Nitrogen for few minutes BY TURNING ON THE VALVE on the nitrogen tank	One can see that there is nitrogen exit from the gas outlets	Positive
Switch on the system	Turn off the nitrogen Turn on the system from the GUI	THE SYSTEM IS GENERATING hydrogen and oxygen	Positive
Burn the hydrogen	Turn on the transformator	The Hydrogen is burning	Negative
Switch off the system	Switch off the system from the GUI Switch off the transformator	The system goes down	Positive
WASH THE SYSTEM WITH NITROGEN	Wash the system with Nitrogen for few minutes BY TURNING ON THE VALVE on the nitrogen tank	All the hydrogen existing in the pipe system exit	Positive
Postcondition	System is off

After correcting the KOH concentration, we started the test and successfully generated hydrogen.
However, the quantity was very low, so ignition did not occur.

Test analysis :

It can be 2 Reason for the low generated quantity :

1- Either the concentration is yet too low knowing that we rise it .

2- Or the current passing through the cells is too low .

or the two reasons together .

what we have to do :

Do a test with the maximum possible concentration of the KOH. If this is not successful we have to define which power supply should be used instead . this is done by installing measuring instruments to detecct the voltage and the current passing through the cells .
