OUR TECHNOLOGY
AEM
MDE has created an Anion Exchange Membrane (AEM) electrolyzer, which is a new technology with promising benefits – yet to be explored fully in a wide-spread commercial application. Compared to PEM and alkaline systems, AEM electrolyzers can allow for a lower degree of water purity (less feedstock cost), significantly lower material/capital costs for metal catalysts, and provide similar or better hydrogen purity and adaptability than fluctuating power sources.
Anode and Cathode
The designs for the anode and cathode are based on research conducted and authored by MDE’s Chief Science Officer.
The anode design provides for a highly active, corrosion-resistant, and substantially 100% selective (without Cl2 evolution) oxygen evolution reaction in alkaline seawater. In addition, the catalyst layer is well-suited for industrial-scale production as it can be easily formed via a single-step electrodeposition reaction.
The cathode is designed such that the catalyst's hydrogen activity and electrochemical stability rival platinum while using significantly cheaper materials.
Both these technologies are yet to be used in industrial applications and MDE would be the first to apply these catalysts.
Elimination of
bipolar plates
The traditional structural purpose of bipolar plates has been replaced with lower-cost, easily mass-produced materials that – unlike metal plates or blocks – can have clever and complex fluid and gas channel designs without additional manufacturing processes (i.e., CNC’ing fluid labyrinths in conductive metal).
