Step	Step Description	Expected Result	RESULTS
Precondition	System is off
THE CHANGING F THE POWER SUPPLY WIT A POWER SUPPLY OF HIGHER VOLTAGE	Replacing the power supply with the welding machine	more hydrogene is generated	positive
open the valves V1 and V1	open the valves V1 and V1 from the GUI	the valve v1 anv d v2 are open and enable to let the nitrogene gas pass	positive
WASH THE SYSTEM WITH NITROGENE	Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank	-one can see that there is nitrogene exit from the gas outlets	positive
Switch on the system	Turn off the nitrogene Turn on the systeme from the GUI	THE SYSTEM IS GENERATING hydrogene and oxygene	the systeme is generating hydrogene but not oxygene
Burn the hydrogene	Turn on the transformator	The Hidrogene is burning	positive
Switch off the system.	Switch off the system from thGUI Switch off the transformator	The system goes down.	positive
WASH THE SYSTEM WITH NITROGENE	Wash the system with Nitrogenen for few minutes BY TURNING ON THE VALVE on the nitrogene tank	All the hydrogene existing in the pipe systeme exeit	not done yet
Postcondition	System off the systeme	systeme is off

After replacing the power supply with the welding machine, we were able to generate enough hydrogen to burn it. see the pictures below .

Fig 1 : the Hydrogene flame

Fig 2: How it looks without falme

But what we noticed is that the current going to the welding machine was only high at the beginning of the start-up (about 13 A at 230 V) and then it kept decreasing until it went down to 1,4 A at 230 V. see the pictures below :

Fig 3 : Just after starting the machine (1A is going to the transformator)

Fig 4 : After a while . One can see how much the current has decreased.

Test analysis :

The welding machine is not good enough since it cannot withstand for long time.

At the highest power of the welding machine, hydrogen was generated and burned, but even then too little.

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 :

1- Test whether the membranes are ruptured.

2 - Doing 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 .
