WHOLE SYSTEME TEST WITH WITH ONLY ONE CELL CONNECTED 05.07.2022

tested according test specification 00005: WHOLE SYSTEME TEST WITH WITH ONLY ONE CELL CONNECTED

Step	Step Description	Expected Result	RESULTS
Precondition	System is off
CONNECTING THE COMPLETE VOLTAGE TO ONLY ONE CELL	DISCONNECT THE POWER SUPPLY FROM TWO CELLS AND CONNECT IT TO ONLY ONE CELL.	MORE CURRENT WILL DRIVE THROUGH THE CELL	Instead of 0.5 A, the power source has drawn up to 5 A from the 230 V socket.
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 NITROGENE	Wash the system with Nitrogen for few minutes BY TURNING ON THE VALVE on the nitrogen tank	One can see that there is nitrogene 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	There is seen that only hydrogen is generated but this is so also in all previous tests we done
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	Turn-off the system	System is off

We have assumed that the voltage we give to one cell is too low, so we have connected all the voltage that was intended for all three cells to only one cell.

We expected more current to go through the one cell. And that is what happened and more hydrogen was generated. But the amount of hydrogen was not enough to burn it.

Fig 1: In the figure it can be seen that only one cell is connected

Test Analysis:

One can see that the resistance of the 3 cells is too high.

What to do:

1- Test whether the membranes are ruptured.

2- Rise the KOH concentration to the maximum.
