Microporous Layer/Catalyst Layer Integration For Electrolyzers

Tech ID: 33662 / UC Case 2024-924-0

Brief Description

This invention combines the attributes of existing catalyst layer architectures to optimize reactions in solid polymer membrane electrolyzers.

Full Description

Researchers at UCI have developed a technology that integrates the catalyst layer and microporous layer in electrolyzers, aiming for both high electrochemical surface area and electrical conductivity. The traditional catalyst-coated membrane architecture is enhanced by affixing needles to microporous layers that electrically tether the catalyst layer and the microporous layer, a process comparable to an internal electrochemical "welding".

Suggested uses

  • Can be utilized in solid polymer membrane water electrolyzers, including proton exchange membrane water electrolyzers and anion exchange membrane water electrolyzers

Advantages

  • Combines the advantages of catalyst-coated membranes and porous transport electrodes
  • Increase in electrical conductivity in comparison to tradition setups
  • Potentially reduces the cost of operation of solid polymer membrane water electrolyzers
  • Allows for decrease in catalyst loadings while preserving electrical conductivity

Patent Status
