Flooding and salt in zero-gap CO₂ electrolysers

Zero-gap membrane electrode assemblies reach industrial current densities, but their cathodes flood and fill with (bi)carbonate salt within hundreds of hours.

Bicarbonate-fed bipolar-membrane electrolysers

Bicarbonate electrolysers convert captured carbon directly, without regenerating and compressing CO₂ gas: protons from a bipolar membrane release…

Completed projects

Bipolar membrane modelling

Bipolar membranes split water at the junction between a cation- and an anion-exchange layer, driven by strong local electric fields.

Mass-transport limits in a microfluidic GDE electrolyser

Gas diffusion electrodes deliver CO₂ to the catalyst in the gas phase, but performance is still set by how fast reactants and products move through…
