Proton Exchange Membrane Electrolyzer Hydrogen Production

 

1. Compact Design

Featuring a high operating current density ranging from 1.5 to 3A/cm², with the core tank area thickness less than 1m and a skid-mounted integrated auxiliary control system.

2. Optimal Efficiency

Boasting DC power consumption below 4.3 kWh/Nm³, coupled with a thermal efficiency exceeding 75% and employing PEM membrane electrodes of top-tier international standards.

3. Versatile Expandability

Designed with a compatible assembly program and flexibility to meet various tank parameters, all seamlessly integrated into a skid-mounted platform.

4. Rapid Responsiveness

With hot starts initiating within 5 seconds and cold starts under 300 seconds, the system easily adapts to load variations ranging from 5% to 120%. Additionally, its verified cyclic start/stop performance ensures longevity.

5. Enhanced Safety Features

Incorporating a self-developed dual-wire sealing design program, along with multi-gas sensor monitoring and alarm interlock system. Precise control of pressure, temperature parameters, and hydrogen production circuit logic adds another layer of safety assurance.

 

 

1. High hydrogen production capacity

The hydrogen production capacity of this PEM electrolyzer is 200Nm³/h per cell, which means it can meet large-scale industrial applications and provide solid support for the accommodation of clean power.

2. Low energy consumption

While focusing on high productivity, this electrolyzer also highlights its energy efficiency. Its DC power consumption is only 4.3kWh/Nm³, which consumes far less energy than traditional electrolyzers. This design reduces production costs and also demonstrates a commitment to sustainable development.

3. Upgraded hydrogen purity

The purity of hydrogen is more than 99.9% before purification, which can be elevated to more than 99.999% after purification. This high-purity hydrogen is critical for applications to fuel cells and other fields.

4. Stable working parameters

4.1 Working pressure: The working pressure is 3.0 MPa, ensuring that the hydrogen produced is at 3.0 MPa, which can adapt to the needs in different scenarios and reduce the cost of further pressurization.

4.2 Working temperature: At an operating temperature of 70±5℃, the electrolyzer is outstanding in terms of stability and adaptability.

5. Power fluctuation range

Power adjustment range is from 5% to 110%. The wide range of power fluctuations allows the electrolyzer to run despite drastic fluctuations in the power system.

6.Quick start technology

Short duration of hot and cold starts: A cold start only takes less than 5 minutes, reducing the duration of production stagnation. A hot start takes only 5s, and the equipment can reach the best working condition in a short time.
