METHODS FOR TESTING ANODE INTEGRITY DURING FUEL CELL VEHICLE OPERATION

摘要

A system and methods are provided for testing anode integrity during vehicle operation. In one particular example, the system and methods allow for anode leak tests during vehicle operation by temporarily reducing fuel cell power while supplementing the fuel cell power reduction with battery power to meet operating demands. In this way, an anode leak test can be performed even during highway driving when operating demands may be particularly high.
