Typically operating over 2 A/cm 2 , MEA electrolyzers can achieve a higher hydrogen yield in water electrolyzers, compared to traditional alkaline systems. Eliminating the gap between electrode and membrane, the catalyst layers or coated gas diffusion electrodes are pressed to the bipolar flow field plates or bonded directly onto a solid polymer membrane. With no liquid electrolyte between the membrane and the catalyst, the membrane itself conducts ions, then gases or reactants are fed to the back of each electrode through flow field plates. This cell architecture is widely recognized for its usability in up-scaling green hydrogen production and CO 2 reduction. The sandwiched central membrane provides a selective, robust barrier which prevents the mixing of produced hydrogen, oxygen, or reduced CO 2 products for high-purity gaseous outputs.

Gas diffusion electrode or catalyst coated membrane: the catalyst is applied to the gas diffusion electrode or on the membrane surface. Gas diffusion layers (GDL): porous materials (carbon paper, nickel foam, titanium mesh) that distribute reactant gases and conduct electrons. Flow field plates: machined plates with serpentine, parallel, mesh, or hybrid channel geometry direct gas flow across the GDLs and provide electrical contact. Observation window (optional): t ransparent acrylic windows support further analysis. Membrane Types The membrane is the most consequential design
