Demonstration hydrogen electrolyser 

Douna has built an hydrogen electrolyser with off-the-shelf components based on the following criteria:

• Robust
• Simple
• Analog 0-5V input-output signal
• And mainly: Readily scalable to larger plants

The last point is very important: the electrolyser is in fact arranged to contain most of the main components of a larger plant, but placed in a smaller and more orderly setup.

The E-power supply is controllable with several types of control signals, including digital.

This power supply goes up to 6kW, and can be connected directly to three phase current.

The output of this power supply is direct current up to 200A.
