Large-scale application of square atmospheric-pressure electrolyzers is accelerating, making them the mainstream choice for green hydrogen mass production.

Square atmospheric-pressure electrolyzers are gradually replacing traditional circular high-pressure electrolyzers and have become core equipment for large-scale green hydrogen production at the current stage.

Based on safe atmospheric-pressure operation, such electrolyzers feature modular stacking and easy capacity expansion, with a single-unit hydrogen production capacity ranging from 1000 to 4000 Nm³/h at high power levels. Compared with high-pressure models, they have lower pressure resistance requirements, more convenient operation and maintenance, and lower leakage risks. Meanwhile, their current density and energy efficiency indicators fully surpass those of traditional circular electrolyzers, with a notable reduction in overall capital investment and operation & maintenance costs.

With excellent adaptability to renewable electricity, high safety, and cost performance, square atmospheric-pressure electrolyzers have become the preferred equipment for large integrated wind-solar hydrogen production projects and centralized green hydrogen bases.
