DOPPELPUMPEN-BRENNSTOFFZELLEN-TEMPERATURVERWALTUNGSSYSTEM |
摘要 |
The outflow of coolers or water transport plates of a fuel cell stack ( 15 ) is fed to the inlet of a gas/liquid separator ( 12 ), the liquid output of which is connected through a primary pump ( 11 a) to a liquid accumulator ( 21 ). A secondary pump ( 44 ) connected to the liquid output ( 20 ) of the liquid accumulator is fed to the principal inlet ( 31 ) of an eductor ( 32 ), the secondary inlet being connected to the gas output of the gas/liquid separator. The outlet ( 37 ) of the eductor is fed through a conduit ( 38 ) to a point below liquid level in the liquid accumulator. Thus, failure of the secondary pump ( 44 ) will not cause cavitation of the primary pump ( 11 a) through the eductor so that coolant will continue to flow through the fuel cell stack. A demineralizer ( 26 ) is fed through a pressure reducing orifice ( 25 ) from the outlet of the secondary pump. |
