Note: 1. You can use Horizon Fuel Cell software Adaptor FCJJ-24 to measure the fuel cell performance
before and after the hydrogen purging process to have a clear view of the impact of this process on the
fuel cell.
2. You can conduct the hydrogen purging process at any time if the load stops working while the hydro-
gen still remains in the container.
3. If the fuel cell is used for the first time to power a load it is highly recommended to follow the hydrogen
purging process as on page 21.
Maximizing hydrogen utilization and optimizing application run-times
There will be some nitrogen in the system and you will have to get rid of it to make your applications work. In
order to maximize hydrogen utilization, the key is to avoid having air (nitrogen) inside your hydrogen fuel cell
system. In order to achieve this goal, we must operate several steps.
Make sure you have your reversible fuel cell module and hydrogen storage modules connected to each other
and there is still hydrogen left in the inner hydrogen container. The load is connected to the whole system.
Using your thumb and index finger, strongly pinch the short tube located
on the reversible fuel cell (C) so that no air passes through the tube.
Keep pinching the tube.
While you keep pinching the tube, remove the black plastic pin (see
picture A).
Very slowly decrease pressure on the tube between your fingers.
There will come a point where gas will start coming out (and very
quickly!). As you do this, keep looking at the hydrogen in the hydrogen
tank to make sure you don't release too much. Be quick and agile
enough to release just a very tiny amount of gas and pinch the
tube back again quickly to keep the maximum gas in.
Keep pinching the tube as you replace the black plastic pin. Once the
pin is back on the tube, you can let go (see picture B).
The load should work better than before due to some impure gases
having been removed.

Create your own fuel cell powered application!
Use the hydrogen and oxygen storage system to power the applications of your imagination. You can
remove the fan blade from the motor and use this motor as your mechanical drive. Remember to
keep your power requirements low as this will reduce the drain on hydrogen. Feel free to submit
pictures and comments on your application developments to [e-mail] for our feed-
back.
Additional Experiments:
You can use Horizon Fuel Cell Software Adaptor FCJJ-24 (not included) to visualize experiments on you
screen or to measure the fuel cell performance before and after the hydrogen purging process to have a
clear view of the impact of this process on the fuel cell. Also you can use Horizon Fuel Cell Software
Adaptor FCJJ-24 to perform your additional experiments.
