Improved lifetime of automotive application fuel cells with ultra-low pt-loading
The main objective of project IMPACT is to increase the life-time of fuel cells with membrane-electrode assemblies (MEAs) containing ultra-low Pt-loadings (< 0.2 mgcm-2) for automotive applications. A durability of 5,000 hours under dynamic operation conditions with ultra-low loadings is required. IMPACT aims at improving significantly durability at reduced platinum loadings by material, component and MEA developments. Detailed analysis of degradation processes are utilized for the derivation of mitigation strategies. IMPACT aims at providing a cost analysis and an evaluation of the technical feasibility for large scale utilization.
The expected impact of this project are aligned along the following aspects:
- Reduction of Pt-Loading, improved lifetime by improved components (catalysts, catalyst layers, membranes, improved operating strategies);
- Assessment of the technical feasibility and cost for large scale production.
The main objective of the project IMPACT is to increase the life-time of fuel cells with membrane-electrode assemblies (MEAs) containing ultra-low Pt-loadings (< 0.2 mgcm-2) for automotive applications. The economic requirement to reduce Pt loading in polymer fuel cells leads to the challenge to concurrently maintain durability and performance. A durability of 5,000 hours under dynamic operation conditions with ultra-low loadings is required for automotive applications. IMPACT aims at significantly improving durability in the automotive application at reduced platinum loadings by material, component and MEA developments. Development is performed on the main components of the cell; namely the membrane, the gas diffusion media and the catalyst and catalyst layers. The basis for the durability is extensive testing at the industrial and research partners’ facilities under diverse and highly dynamic conditions and comprehensive and detailed analysis and evaluation of degradation processes and their importance for fuel cell performance loss. This analysis is utilized for the derivation of mitigation strategies by component modification and optimization of operation modes. The mitigation strategies are experimentally validated and consecutively lead to a demonstration of the improved durability in a predefined stack. IMPACT also aims at providing a cost analysis and an evaluation of the technical feasibility for large scale utilization of the project achievements. Recommendation and dissemination activities are planned within scientific workshops, publication of the results in scientific journals, and using project fact sheets.
