The preparation of the outside air before it is fed to the fuel cell is of particular importance. MAHLE air filters protect the fuel cells from particles and harmful gases with absolute reliability and throughout the entire service life of the vehicle. A modular concept makes the application simple and cost-effective.
The MAHLE flat membrane humidifier is a key component for the reliable operation of fuel cells.
In order to be able to work optimally, fuel cells need humid air. MAHLE’s flat membrane humidifier accomplishes this. It increases efficiency and protects the cell from drying out. Reliable humidification is also very important for maintaining a level of efficiency and contributes to the long service life of these expensive components. MAHLE developed the flat membrane humidifier in conjunction with other partners. This development was sponsored by the Federal Ministry for the Economy and Climate Protection (BMWK). In order to stabilize the voltage provided by the fuel cell across all load ranges, the company has developed a high-voltage DC/DC converter. It covers high outputs of up to 180 kW, reaches an efficiency of more than 97 percent and achieves very high power density. Together with the sophisticated thermal management, MAHLE thus maps the essential systems in fuel cell peripherals.
