Anion Exchange Membranes

Dioxide Materials is developing Anion exchange membranes (AEMs) which can be used in technology that will help address three key megatrends:

  • Global warming/greenhouse gas emissions
  • Shift to renewable energy, need for energy storage, energy poverty, & energy independence
  • Shift from fossil fuels to renewable fuels and chemicals

Comparison of the conductivity of new Dioxide Materials™ membranes to the best that have been reported in the literature in 1 M KOH.

Sustainion™ Membranes & Ionomers

Polarization Curve varies with different amounts of XA catalyst additive in cathode layer
  • Polarization curve varies with different amounts of Sustainion™-XA5 to the cathode layer in a cell with a Sustainion™-XM4 membrane.
  • We can obtain currents of 1.4 amps (280 mA/cm²) at 3 volts with a Sustainion™-XM4 membrane and Sustainion™-XA5 ionomer.

Sustainion™-XM1 membrane and an optimal amount of Sustainion™-XA7 in the cathode catalyst layer

Sustainion™-XA6 in the catalyst layer

We can maintain 600 mA/cm² at between 3.25 and 3.35 V.
