Air-cooled PEM Fuel Cell Membrane Electrode Assemblies

Compact air-cooled MEA solution for simplified PEM fuel cell system integration.
Stable operation under dry-air and variable-humidity conditions.
Supports open-type and closed-type stack configurations.
Reliable power output with reduced dependence on external humidification and liquid-cooling systems.
Suitable for lightweight mobility, portable power, UAVs, and backup power applications.

Air-cooled PEM Fuel Cell Membrane Electrode Assemblies

The Air-cooled PEM Fuel Cell MEA is a core electrochemical component designed for PEM fuel cell systems that require compact structure, stable power output, and simplified balance-of-plant configuration. It is particularly suitable for applications where liquid-cooling and complex humidification systems are not preferred.
The F70 air-cooled MEA is engineered with optimized catalyst layers, proton exchange membrane interfaces, and gas diffusion pathways to support efficient hydrogen oxidation, oxygen reduction, proton transport, and water management under air-cooled operating conditions.
The product supports both open-type and closed-type air-cooled system designs. Under specified test conditions, it maintains stable voltage performance at rated current density and demonstrates strong tolerance to cathode humidity variations, making it suitable for practical operating environments with fluctuating ambient humidity.

Key Features

Stable Operation under Dry-air Conditions
- Optimized for non-humidified or low-humidity operation, supporting stable performance under dry ambient air conditions.
Broad Humidity Adaptability
- Maintains reliable voltage output across a cathode humidity range of 0–70% RH, improving adaptability to different operating environments.
Open-type and Closed-type Compatibility
- Applicable to open-type fan-driven air supply systems and closed-type air-cooled stack configurations according to customer system requirements
Reliable Rated Power Performance
- Provides rated performance above 0.60 V at 1.0 A/cm² for open-type systems and above 0.65 V at 1.2 A/cm² for closed-type systems.
