Learn about how to test a fuel cell system, ensuring its reliability and performance in this Hyfindr Tech Talk. Testing involves supplying hydrogen and air, managing exhaust and cooling, and monitoring safety features like hydrogen sensors and ventilation. At Nuvera Fuel Cells facility, they test multiple modules simultaneously, using a hydrogen supply from a nearby gas producer. They maintain equipment calibration for consistency and run systems for extended periods, accumulating thousands of hours of operation. Reliability is assessed by defining a test plan based on application-specific load profiles, running performance checks, and ensuring safety through proper ventilation and sensors. The facility also prepares for larger and more advanced systems.

Executive Summary of Tech Talk Script:

In this Hyfindr Tech Talk, Katia Franchi, Leader of Product Test and Support Europe from Nuvera Fuel Cells discusses testing of fuel cell systems, that involves multiple steps to ensure its reliability, performance, and safety. The process begins by supplying hydrogen and air to the system, with hydrogen sourced from a nearby gas production facility. The exhaust, cooling, and safety mechanisms are also critical components. Exhaust is managed through a water separator that condenses and removes liquid water from the stream, while cooling is handled by radiators and heat exchangers to dissipate the heat generated by the system.

At Nuvera’s facility, they have an engine test module capable of testing multiple E45 or E60 modules simultaneously, each producing 45 or 60 kilowatts of power. These tests can be run in parallel or independently, continuously monitoring various parameters. The facility is equipped with sensors and ventilation systems to ensure safety, particularly by preventing the formation of explosive atmospheres. Hydrogen sensors continuously monitor concentration levels, while ventilation fans extract air from the enclosed testing containers to maintain a safe environment.

The testing process includes a detailed test plan focusing on the reliability growth of the system, based on the load profiles of different applications. This involves running the system for extended periods, sometimes accumulating tens of thousands of hours of operation. For instance, they have accumulated 37,000 hours of running time on the E45 and E60 systems. Consistency is ensured by maintaining equipment calibration and using redundant sensors to verify measurements.

Performance checks are conducted to ensure the product meets expected standards. This includes factory acceptance tests repeated at the facility to verify consistent results. The tests involve varying power levels to observe changes in voltage and current, ensuring stability at maximum power.

Nuvera is also developing new systems, such as a 125-kilowatt proof-of-concept, which are in the pre-phase of production. The facility aims to continue active testing for reliability and qualification of new materials, focusing on extending the lifetime of the fuel cell stack and integrating larger systems.
