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 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 |
there is seen that only hydrogene is generated but this is so also in all previous tests we done |
Burn the hydrogene |
Turn on the transformator |
The Hidrogene is burning |
negative |
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 |
positive |
Postcondition |
System off the systeme |
systeme 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 cellls is too high .
what to do :
1-Test whether the membranes are ruptured.
2-Rise the KOH concentration to the maximum.
