Flood-Resistant Membrane-Electrode Assemblies

Hydrophobic-gradient MEAs that run for weeks without flooding.

The problem

Gas-diffusion electrodes flood as salts precipitate, collapsing performance within hours.

The approach

Engineer a wettability gradient through the catalyst and transport layers to expel liquid water.

Key results

1000 hours of stable CO₂ electrolysis with less than 10% performance loss.
