Chinese electrolyser original equipment manufacturer (OEM) Shuangliang claims to have set a new industry record for current density in its 5,000Nm3 alkaline system.
When operating at 90oC, the OEM says the electrolyser can reach 10,600A/m2 as a maximum current density, with an energy consumption of 4.7kWh/Nm3.
Higher current density means greater hydrogen production capacity, but maintaining this with low energy consumption is difficult, with most electrolysers operating at lower current densities.
