Proton Exchange Membrane Fuel Cells (PEMFCs)are electrochemical energy converters, suitable for poweringelectric vehicles. However, for now, fuel cells fail to compete withtraditional internal combustion engines (ICE). One of the reasonis their limited durability and reliability compared to ICE whichhave a lifespan of around 8000h. One solution to improve fuelcell durability is to optimize the PEMFC operating conditions.This is possible by implementing an embedded fault tolerantcontrol in the vehicle control system. In this context, this paperpresents a Modified Failure Mode and Effect Analysis (MFMEA)for PEMFCs. An FMEA is an engineering tool that lists all failuremodes a system can experience in a table. In this table, rankingsdefine the criticality that the failure has for the system. In thisarticle, a MFMEA is used as a fault tolerant control apparatus.For this, the MFMEA is coupled with a diagnosis tool. From theresults provided by the diagnosis tool, the MFMEA evaluatesthe criticality of the failure by calculating a Risk Profile Number(RPN). Afterwards, corrective actions are proposed based on theRPN value
