Mentum has developed an innovative electrolysis membrane cell introducing new materials allowing alternative assembly methods improving performance, cost-efficiency as well as operational window.

The starting-point for the development was to enable the cell to use seawater as an electrolyte without any form of pre-treatment. The main challenge related to this is the presence of Magnesium in seawater taking part in the electrochemical reactions and forming a substrate of the mineral form of Magnesium Hydroxide (Mg(OH)2) or Brucite as it often is referred to. This tends to clog conventional membrane cells. The new development reduces the impact of Brucite.
