An observable MEA electrolytic cell in which a central ion-conducting membrane is sandwiched between a catalyst-loaded anode and cathode, sided by gas diffusion layers. The transparent sections are made of acrylic, and the outermost layers on the left and right are hollow metal pressure plates to secure the device and accommodate the observation windows. With a 'zero-gap' design, direct contact of the catalyst and membrane enhances the catalytic reaction performance by improving mass transfer and enabling high current densities.
The membrane electrode assembly is the core unit where catalytic electrochemical reactions happen. The ion-conducting membrane could be a proton exchange membrane (PEM) or anion exchange membrane (AEM) to allow exchange of proton or ions for efficient hydrogen production by AEM or PEM water electrolysis. The membrane allows ions to migrate while prevents the gas permeation and products to mix, which is critical for efficiency and safety in applications like fuel cells and water electrolysis. The membrane also separates the anode and cathode, providing electrical insulation between the two sides of the cell.
This electrochemical cell is an effective system for carbon dioxide reduction reaction, a process that uses electrical energy to convert carbon dioxide into other valuable chemical products. In additions, this MEA electrolytic cell can also be employed for seawater electrolysis, electrosynthesis of cyclohexanone coupled with hydrogen production, electrosynthesis of chlorine, lithium-mediated nitrogen reduction reaction, i.e. ammonia synthesis, electrochemical urea oxidation, and electrocatalytic waste polyethylene terephthalate recycling.
