Frequent start/stops limit the lifespan of our AEM electrolyser stack, as is the case with all electrochemical devices. We can now advise our customers to restrict the electrolyser’s operating cycles to no more than five on/off cycles per day and one on/off cycle per hour due to our growing field experience and operational data. This contributes to the electrolyser’s lifetime.
Continuous operation maximizes the electrolyser’s durability and efficiency. However, the Agastya Energy Management System and our modular architecture are ideal for accommodating varying demand or a shifting renewable energy supply. You can ramp up individual ELs from 60 to 100%, and you can obtain any required flowrate by combining multiple ELs. Adding a buffer tank of the right capacity helps reduce the electrolyser’s on/off cycles if the demand for hydrogen fluctuates throughout the day.
Since the majority of the mineral ions have been eliminated, deionized water has a poor conductivity. Ions can become trapped in the stack membrane when non-purified water is used, which will shorten the stack’s lifespan. Over time, the performance of the stack may also be impacted by persistent contaminants.
Because they are all the same width and depth, electrolysers, dryers, and water tank modules can be stacked in 19″ cabinets. Even more hydrogen can be produced by combining multiple cabinets.
The gadgets’ lifespan will be shortened in corrosive situations. Therefore, if the requirements cannot be met in any other way, it is always advised to maintain them in a room or container with controlled humidity and temperatures.
As specified in the product documentation, the devices must be installed horizontally. Very slight slopes up to 10°, however, have no detrimental effects on the operation or functionality of Agastya devices. For more details, please refer to the product handbook.
Yes, the P&ID is available here and in the electrolyser’s owner’s handbook. While the H2 Out can be linked to the dryer, the H₂O In can be connected to the WTM (Water Tank Module).
To prevent blockages in the outlet pipes, it is advised to use water traps: one for the O₂ vent line and another for the H₂ vent line. Water traps of the float type with an automated drain system are what we advise. Verify if KOH is compatible with both water traps.
In order to eliminate water from the electrolyser and improve the quality of the hydrogen at the hydrogen outlet, the purge line is utilized every 12 hours throughout operation and during ramp ups and ramp downs. The water extracted during the drying process is contained in the dryer’s purge line, which can be linked to one of the electrolysers.

The ideal temperature and pressure are always used in our stack. Consequently, the only factor influencing the polarization curve is the production rate. It is covered in the aforementioned chapter on “The electrolyser in general.”
There are 23 cells in each stack.

Agastya only uses its own developed Anion-Exchange-Membrane (AEM).
The stacks in the Multicore are always liquid cooled.
