SHUTDOWN PROCEDURE
To shut down the fuel cell system down, please follow these steps:
1. Turn off the load.
2. Hold the ON/OFF button down for 2 seconds to stop the system, you will hear one long beep,
which means the system is shutting down.
3. Turn the hydrogen supply off.
4. Disconnect the hydrogen supply tube from the hydrogen inlet as shown in the picture below.
WARNING:
Disconnect the hydrogen tube from the hydrogen inlet immediately after the fuel cell stack is shut down.
Since hydrogen gas can leak into the fuel cell and destroy the stack.
If the fuel cell is not in use, please follow these final steps.
Disconnect the external power supply from the controller.
Completely disconnect the fuel cell system from the load.
Completely disconnect the fuel cell system from the controller.
Let the fuel cell cool down before placing it into an air tight container. This will help to maintain its
performance particularly during long periods of storage.

Note: When you turn off the on/off switch connected
to the control box at the temperature of the fuel
cell stack higher than 45˚C the stack will not
stop working immediately. Only when the stack
temperature goes down below 45˚C, the whole
system will stop operation in order to protect the
stack. So in order to make it work well, the fuel cell
stack must be maintained lower than 45˚C before
operate the on/off switch.
