Report on the investigation of the impact of contaminants in H2 and air contaminants on PEM Fuel Cell (FC) (reliability) and durability (sustainability)
under short-term and long-term operation, including recommendations for air quality sensors needed for monitoring FC systems.
This report documents the investigation of the impact of complex mixtures of impurities in hydrogen and air on PEMFC under short-term and long-term operation as carried out at NPL.
This work was carried out at NPL with the assistance of CEA, UDC and Reganosa (while this company was involved in Mefhysto, before they left it) as part of WP3 of the MefHySto project and is a resume of the NPL’s, CEA’s and UDC’s contributions to Deliverable 4. To the knowledge of the authors, this is one of the first instances where a complex mixture with more than three contaminants has been used to poison a fuel cell. As such, the work performed ostensibly represents a worst-case scenario of fuel cell poisoning on the basis of the ISO 14687:2019(D) standard which specifies the threshold limits for each contaminant in hydrogen for vehicular applications.
