Catalyst Coated Membranes:
Catalyst coated membranes (CCM) are membranes that have had a catalyst layer deposited directly on either side of the membrane, instead of onto a Gas Diffusion Layer (GDL). These are often referred to as 3 layer CCM’s. It allows the user to then add their own gas diffusion layers to make a complete membrane electrode assembly.
EES CCM manufacturing capabilities are as follows:
| Membrane options: | |
|---|---|
| Membrane type | Nafion NR212 |
| Nafion XL | |
| Nafion HP | |
| Standard sizes (cm2) | 1, 5, 25, 50, 100, 200 cm2 |
| Custom active area size | Up to 28 x 45 cm |
| Border area | Up to 60 x 60 cm |
| Catalyst options | 0.2-0.4 mg/cm2 Pt loading on VULCAN XC72. |
EES CCM’s can come as the following 4 variants:
| 3 layer CCM for humidified operation | EESCCM-H |
| 3 layer CCM for self-humidified operation | EESCCM-D |
| 3 layer CCM for oxygen operation | EESCCM-O |
| 3 layer CCM - customised | EESCCM-C |
