in them. Unipolar are easier to build, operate, maintain and use of the water supply pump to be generally
lower operating pressure less electrolyser, these electrolysers produce hydrogen at low pressure and for
the same production of hydrogen occupy more bipolar space. The electrical connection of them is also
more complex because each cell must be powered independently.
Bypolar have the advantage that they can be pressurized, causing hydrogen pressure, which increases
the energy efficiency of the installation by not needing compressing equipment hydrogen at low pressure.
Besides the electric connection of the cells is easier since only the source is connected only to the ends. In
