Core Positioning

Extending Hydrogen Energy Technology into Specialized Dehumidification Components

Unlike traditional refrigeration-based or compression-based dehumidifiers, H2gatech’s products are centered on electrochemical dehumidification MEAs and modules derived from hydrogen fuel cell MEA technology. These products are not complete dehumidifier units, but rather high-performance core components that can be integrated into specialized dehumidification systems for industrial and precision-use scenarios.

By leveraging its strong technical foundation in hydrogen energy materials, H2gatech is advancing the localization of high-end electrochemical dehumidification technology and supporting the domestic substitution of imported core components in this field.

R&D Objectives

With its expertise in catalyst formulation, proton exchange membrane development, and water and thermal management, H2gatech focuses on solving key pain points found in conventional dehumidification equipment, including:

• High energy consumption

• Large equipment footprint

• Instability under low-temperature and high-humidity conditions

• Insufficient humidity control precision in sensitive applications

The company is committed to developing high-efficiency electrochemical dehumidification products that meet the needs of a wide range of advanced industrial environments.

Core Technology

Electrochemical Dehumidification for High Efficiency and Energy Savings

H2gatech’s dehumidification technology originates from the core processes used in hydrogen fuel cell MEAs. It inherits the fundamental advantages of efficient moisture separation, proton conduction, and selective water vapor transport, enabling cross-application reuse of hydrogen energy technology.

Key technical features include:

• Selective moisture transport through proton exchange membranes
  Under low-voltage and low-current operation, water vapor can be directionally transported and separated, enabling effective dehumidification without consuming target gases such as hydrogen or air.

• No condensation, refrigerant, or mechanical moving parts
  This enables silent, vibration-free operation, making the technology especially suitable for compact, precision, or harsh industrial environments.

• Advanced in-house process development
  Proprietary technologies including low-platinum catalyst coating, gradient pore structure design, and reinforced membrane–catalyst interfaces significantly improve dehumidification efficiency, selectivity, and mechanical durability, forming the technological core of the product platform.

Product Performance

Strong Multi-Dimensional Performance for Complex Operating Conditions

Following multiple rounds of laboratory evaluation and third-party testing, H2gatech’s electrochemical dehumidification MEAs and modules have demonstrated performance comparable to advanced international standards.

Typical performance highlights include:

• Humidity operating range: 30%–90% RH
  Stable operation across a wide humidity range, with reliable performance in both high- and low-humidity environments.

• High dehumidification selectivity
  Excellent water vapor permeability with low gas crossover leakage, achieving performance 15%–30% above the industry average.

• Low energy consumption
  Low-voltage operation without compressors or other high-power components enables highly energy-efficient performance and reduced operating costs.

• Durability and service life
  Third-party durability testing shows less than 4.5% performance degradation after 1,000 hours, with an expected service life of over 10,000 hours.

• High-precision humidity control
  Humidity response linear error of ≤ ±2%, making the technology suitable for precision humidity regulation in sensitive applications.

• Excellent environmental adaptability
  Supports cold start at temperatures as low as -30°C, making it suitable for harsh conditions such as vehicle-mounted systems, marine environments, and outdoor energy storage.
