Performance Recovery of Fuel Cell Stack for FCEV 2015-01-1171

This paper proposes the several methods for recovering the performance of degraded fuel cell stack for FCEV. Recovery procedure is focused on the reduction of oxidized layer and desorption of sulfonated anion formed on the surface of platinum catalyst during automotive operation at cathode side. As a result of application of recovering methods, it is possible to partially rehabilitate the performance of fuel cell stack by ca. 20-30%. In additions, it is expected that the durability of fuel cell can be improved ultimately with an application of recovery process.
