Membrane Electrode Assembly (MEA) Flow Electrolyzer with Serpentine Flow Channels, CMEAFESFC

An MEA flow electrolyzer (often called a Zero-Gap Flow Cell or MEA-Cell) is a hybrid architecture that combines the high energy efficiency of a Membrane Electrode Assembly with the continuous reactant supply of a flow cell. While standard PEM electrolyzers are "static" in their assembly, a flow electrolyzer is specifically designed for industrial scaling and for reactions like CO2 reduction (CO2RR) or Bicarbonate electrolysis, where managing the flow of liquid electrolytes and gaseous products is critical to prevent system failure.

In a flow MEA, the "gap" between the anode and cathode is eliminated by sandwiching the ion-exchange membrane directly between two Gas Diffusion Electrodes (GDEs). (1) Flow Fields: Bipolar plates with carved channels (e.g., serpentine or parallel) are pressed against the GDEs. These channels continuously deliver liquid electrolytes (anolyte/catholyte) or humidified gases (CO2) to the active sites. (2) The MEA Sandwich: Consists of a membrane (AEM, CEM, or Bipolar) with catalyst layers coated either on the membrane (CCM) or on the Gas Diffusion Layer (GDL).

Unlike a standard electrolyzer where the water is simply "there," in a flow electrolyzer, the fluid dynamics dictate the efficiency. (1) Serpentine Channels: Create a pressure drop that forces reactants into the GDL (convection), which is superior for CO2 transport and preventing "hotspots". (2) Parallel Channels: Offer lower pressure drops but are prone to uneven distribution and gas trapping (slug flow). (3) Zero-Gap Benefits: Minimizing the distance between electrodes reduces ohmic resistance, allowing these cells to operate at industrial current densities of >500 mA/cm2.
