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.
The cell is made entirely of high-purity titanium; high-purity nickel plates are available for special environments (priced separately). The bipolar plates have heating and temperature-measurement holes for constant-temperature testing.
Serpentine, parallel and leaf-vein flow fields are offered; spiral, mesh and comb-type channels can be customised.
| Electrode system | Two-electrode (anode / cathode) |
| Bipolar plate | Titanium (nickel optional) |
| Flow field | 10 × 10, 20 × 20 mm, 5 cm², 30 × 30, 50 × 50, 100 × 100 mm |
| Flow channel | Serpentine, parallel, leaf-vein (custom possible) |
| Sealing | Double O-ring |
Dimensions, channel sizes and volume can be customised on request; please state special requirements in your quotation request.
