3.3.2.7 fuel cell overhaul

Fuel cell overhaul is a specialized maintenance procedure designed to restore degraded hydrogen fuel cell stacks to their original operating efficiency and power density. As fuel cells experience membrane degradation and catalyst wear during flight operations, periodic overhaul is necessary to extend their service life. Challenges in developing this service lie in the current lack of high-volume, cost-effective remanufacturing technologies and standardized testing protocols to certify overhauled fuel cells.
