Research grade hardware needed to build your own Carbon Dioxide Electrolyzer.  Water and carbon dioxide electrolyzers are poised for wide scale deployment as a way of storing renewable energy and as a way of mitigating climate change.

The Dioxide Materials’ development of an alkaline stable Sustainion® membrane enabled the development of zero-gap design CO2 electrolyzers that can improve current density by two orders of magnitude at the same or lower cell voltage as compared to the current diaphragm-based alkaline water electrolyzers.

Dioxide Materials sells individual components so you can build your own CO2 electrolyzers.  Or, you can also order fully assembled “plug and play” CO2 electrolyzers that are shipped in less than 5 business days. The choice is yours.

The development of the Dioxide Materials’ CO2 electrolyzer technology in efficiently producing CO at high selectivities is based on four technological developments. These are:

  • Development of a GDE cathode structure comprising an imidazole-based ionomer as a co-catalyst with nanoparticle Ag, reducing the potential at the cathode for the CO2 reduction reaction
  • Development of a high conductivity and alkaline stable anion membrane (Sustainion® membrane) that can conduct OH and bicarbonate/carbonate ions and imidazole-based ionomer
  • Development and utilization of the Sustainion® imidazole ionomer, that when incorporated with the selected catalyst in the cathode GDE construction, reduces the cathode reaction potential in CO2 reduction
  • Development of a GDE anode structure comprising a nanoparticle IrO2 catalyst

These developments have helped create an electrochemical CO2 technology that can operate at high current densities, high CO selectivity, and low cell potentials.
