FUEL CELL DEVICES FOR FIRE AND/OR EXPLOSION PREVENTION

摘要

Described are fuel cell/inerting systems (12, 20) having at least one fuel cell system (10), at least one dryer coupled en (26) to a fuel tank (40), at least one ODA flow selector valve (28) having a first outlet port coupled to a cargo bay (38), and a second outlet port coupled to the dryer (26), and a controller (36). The fuel cell/inerting system detects an amount of ODA output from the fuel cell system and transmits a signal to the ODA flow selector valve instructing the ODA flow selector valve to open both outlet ports when the controller determines that the amount of ODA output is sufficient to supply the cargo bay (38) and the fuel tank (40) or close one of the two outlet ports when the controller determines that the amount of ODA output is insufficient to supply the cargo bay and the fuel tank. ODA: Oxygen Depleted Air NEA: Nitrogen Enriched Air
