SYSTEMS AND METHODS OF CAPTURING NITROGEN FROM FUEL CELL

Systems and methods are provided for capturing gas byproducts of a fuel cell system, such as nitrogen. Instead of dispelling the gas byproducts, a byproduct management system can engage in selective isolation, compression, and storage of the gas byproducts in various storage tanks. The compression and storage of the gas byproducts can be effectuated using excess energy, e.g., regenerative energy.
