Non-metallic Polar Frame Stack Advantage：

1.No parasitic current on the non-metallic polar frame channel; high current efficiency.

2.Has small volume & light weight compared to the metal polar frame, which is easier to transport for exporting.

3.Innovatively optimized in structure with H2 purity over 99.9% and O2 purity over 99.2% before purification.

4.No electrochemical corrosion after long-term use with a longer lifespan for stack compared to the metal polar frame.

5.The 10-year degradation of non-metallic polar frame stack is as low as 5% due to the low current density operation.

Note: The equipment below CHO-50 can be used as an integrated box structure; the electrolytic cell above CHO-50 should be placed separately; the gas-liquid separation device can be used as an integrated box structure.
