We can manufacture 2-1000Nm3/h hydrogen generator plant with non-metallic material for the polar frame of electrolytic cell. It helps to avoid electrocorrosion, reducing 2/3 volume and 1/2 weight of electrolytic cell. The degradation of our electrolytic cell is less than 5% during ten years. The most important thing of this material can help electrolytic cell quick warm/cold start according to solar/wind energy fluctuation of power supply by comparison with metal material polar frame
