Abstract

The test is addressed to investigate the influence on stack durability of a long stop followed by a restart of a stack. Long stop should be defined as a stop in which the anodic compartment is fully filled by air due to stack leakages. In systems, leakage level of the stack is low and time to fill anodic compartment remains very high and incompatible with evaluation of long stop effect. In this procedure, the complete exposure of the anode to air is made using air present in the cathodic compartment and temperature is maintained to the nominal temperature in order to avoid effect of a thermal cycling.
