The challenge: Increasing the lifetime of a cell and reducing material costs
The proton exchange membrane fuel cell (PEMFC) is the beacon of hope for the mobility of the future.
Valuable properties of fuel cells, such as the high efficiency, compared to combustion engines, as well as the compact design or its good cold-start behavior, make a widespread application of the low-temperature fuel cell highly desirable in local passenger transport or in shipping, for example. The PEMFC is also interesting for self-sufficient electronic systems or for combined heat and power generation.
The greatest challenges in the development of fuel cells materials nowadays are in the handling of
- gas permeability and water management
- thermal and electrical conductivity
- the operation at elevated temperature (350 K)
- mechanical stress and aging
together with the reduction of material costs.
- AI-assisted identification of binders and individual fibers and particles in 3D-image data
- Generation of realistic statistical Digital Twins of the materials at the microscale
- Determination of important geometric and physical parameters
- Quantitative and high-performance simulation of physical properties
- Automated parameter studies for the design of new fuel cell materials
