A membrane electrode assembly (MEA) electrolyser sandwiches a gas diffusion electrode, ion-exchange membrane and anode between cathode and anode flow plates; with no liquid electrolyte gap between the electrodes (zero gap), cell resistance is low and current densities close to industrial scale can be reached.
Designed for temperature-controlled testing of large-area MEA cells (50 × 50, 100 × 100 and 200 × 200 mm). It has a dual control system: thermostatted water jacket plus heating rod and thermocouple.
The cathode and anode channels are multi-pass serpentines; a shear-inducing channel design lowers resistance when used with a high-pressure pump. Current tabs are replaceable gold-plated copper.
