Abstract
Methods and systems for regenerating a fuel cell are disclosed, comprising sparging a catholyte liquid with a gaseous oxygen-containing flow stream. In addition, the gaseous byproducts in the catholyte can be collected and then converted to liquid forms for easy disposal. In some embodiments, the regeneration process comprises intermittently regenerating an oxidant flow stream, for example, based on detected conditions. In some embodiments, the regeneration process comprises switching between different modes of oxidant regeneration, for example, based on detected conditions.
