In this Project present the construction, design and evaluation of a mono polar
alkaline electrolyser using a concrete diaphragm is announced. There are
electrolysers that separate the hydrogen and oxygen gases, although at a high
cost, what is intended when using the concrete diaphragm is to reduce
manufacturing costs as well as being easily accessible to the general population.
In the construction of the electrolyser, 6 20 gauge 304 stainless steel plates were
used, with concrete diaphragms and 1/8 neoprene plates. The stainless steel
presents resistance to corrosion, the dimensions of the steel plates are 15x15
centimeters, the diaphragm.
Within the obtained results, an efficiency of 50% in the transformation of energy
was obtained, a hydrogen production of 300 milliliters per minute with a
concentration of 0.1 molar using potassium hydroxide as electrolyte with a
plate-to-plate spacing of 3.1 millimeters.
