Rehydrating the fuel cell because the stack cannot reach the rated power
1. Make sure the purging valve is disconnected from the hydrogen outlet
connector.
2. Add water to fuel cell through the hydrogen inlet connector, and keep filling until
water starts to come out of the hydrogen outlet valve.
3. Immediately use the hydrogen supply valve to connect the hydrogen supply the
hydrogen inlet connector. Pay attention to the hydrogen supply direction.
4. Make sure the hydrogen supply pressure is not >0.5bar.
5. Open the hydrogen supply. Turn on the on/off switch for purging the water out of
the fuel cell.
6. Steps 1-5 should only take 5-10 seconds to do.
7. Setup the fuel cell system again for general operation.
8. With the SCU switch on, start the fuel cell again.
Battery voltage is too low
Please check if start-up battery connector is ok.
Or the battery might not be operating correctly or in the case of a battery may not
have any charge left.
1. Disconnect the external power source.
2. Using a multimeter take a reading of the positive and negative connection
points on the external power connectors to the controller.
3. If the power is <13.5V then the power is not coming through to be able to power
the controller, blowers and valves.
4. Change or recharge your power supply and check the voltage that it meets the
fuel cell voltage before connecting it up to the controller.
Stack voltage is too low
1. Please check if supply/purge valve is open.
2. Please check if the blowers are running slowly, or not running at all.
Hydrogen leaks
Please check if the gas line has no leakage, including gas tubings and gas
connectors, etc…
If the system shuts down by itself check the following details
1. Make sure you have connected all wires according to the diagram.
3. Make sure you have connected the hydrogen supply with the correct pressure.
4. Make sure the load is below the peak power. Overload can trigger the stack
protection function to avoid the damage to the stack.
5. Check whether the fuel cell temperature is below
68˚C,
the system will shut off if
it is above
68˚C
