METHOD FOR REGENERATION OF SULFUR-POISONED FUEL CELL STACKS

摘要

A method for regeneration of asulfur-poisoned fuel cell stack, preferably a solid oxide fuel cell (SOFC) stack, comprising applying a voltage potential to a fuel cell stack for a period of time sufficient to increase the average cell potential of the sulfur-poisoned fuel cell stack. The regeneration is initiated after a detected performance loss, and the regeneration can be a full regeneration, partial regeneration or a full regeneration and an improvement.
