Aging data based on daily cogeneration profile

The EU-funded project SAPPHIRE (System automation of PEMFCs with prognostics and health management for improved reliability and economy) was initiated to address the relatively short life expectancy of PEMFCs. Extending service life can be achieved in several ways – one of these is prognostics and health management.
Researchers reviewed existing models of PEMFC stacks, employed for state-of-health assessment and even operation control. Project partners also developed several controllers to efficiently counteract common factors that can cause degradation. SAPPHIRE generated two patents, one for the controller system and another for the data-driven prognostic system. By ensuring sufficient durability for transport and stationary applications, SAPPHIRE work promises to accelerate market uptake of fuel cell technologies and promote Europe’s energy independence.
