AI Overview

Proton Exchange Membrane (PEM) water electrolysis technology at a 5000ml/min (5L/min) capacity represents a high-efficiency, small-to-medium scale hydrogen production solution. It is commonly used for laboratory applications, hydrogen fuel cell research, and small-scale industrial applications.

Core Technology & Performance

Production Rate: 5000ml/min (5L/min) or roughly 0.3
$cap N m cubed$
/h of hydrogen.
Technology: Uses a solid polymer electrolyte (Proton Exchange Membrane) to efficiently split pure water into high-purity hydrogen and oxygen.
Purity: Typically produces >99.99% or 99.995%+ pure hydrogen, suitable for sensitive applications like GC (Gas Chromatography) or fuel cells.
Output Pressure: Often rated for operating pressures between 0.2 and 0.5 MPa (20-35 bar/kg).

Stack Design: Frequently features 10-14 electrode stacks utilizing platinum and iridium oxide catalysts on titanium plates.
Membrane: Utilizes advanced proton exchange membranes, such as DuPont N117, for high efficiency.
Power Supply: Generally requires a constant current DC power supply with a current capacity of roughly 60A-70A and voltage under 30V.
Efficiency: Consumes approximately 7-8 kWh/
$m cubed$
of electricity for hydrogen production.
Water Quality: Requires deionized or purified water (conductivity
/cm or even
/cm).

Constant Current Regulation: To prevent damage, a dedicated constant current DC supply should be used.
Temperature Management: Optimal performance depends heavily on operating temperature. Frequent low-temperature startups can cause damage.
Water Separation: Requires a gas-liquid separator (or buffer bottle) to remove water from the hydrogen output before usage.
Maintenance: Generally requires low maintenance but requires regular monitoring of water purity and levels.
