an air compressor comprising at least one air compressor inlet and at least two air compressor outlets,
a networking of hosing comprising at least six hose segments,
wherein a first hose segment comprises a first free end and a second end coupled to the at least one air compressor inlet,
wherein a second hose segment comprises a first end coupled to one of the at least two air compressor outlets and a second end coupled to one of the at least two fuel cell enclosure inlets,
wherein a third hose segment comprises a first end coupled to the at least one fuel cell enclosure outlet and a second free end,
wherein a fourth hose segment comprises a first end coupled to a second of the at least two air compressor outlets,
wherein a fifth hose segment comprises a first end coupled to a second of the at least one fuel cell enclosure outlet and a second end joined to the fourth hose segment at a return point, and
wherein a sixth hose segment comprises a first end joined to the fourth hose segment at a redirection point and a second end coupled to a second of the at least two fuel cell enclosure inlets,
wherein the second hose segment and the third hose segment are comprised by a first flow path while the fourth hose segment is comprised by a second flow path, and
an air stream comprising a compressed air stream and a parasitic loss air stream.
