UNDERWATER RECIRCULATION-TYPE FUEL CELL SYSTEM

The present invention relates to a fuel cell system to be used in an underwater environment such as that of a submarine, wherein the fuel cell system can exhibit fuel utilization of 99.9% or more by the recirculation of a fuel even if simply composed of a single-stage stack, and can minimize complex...

Beschreibung
Zusammenfassung:	The present invention relates to a fuel cell system to be used in an underwater environment such as that of a submarine, wherein the fuel cell system can exhibit fuel utilization of 99.9% or more by the recirculation of a fuel even if simply composed of a single-stage stack, and can minimize complex gas-liquid separation control according to a multi-stage stack. In addition, the fuel cell system does not use pure oxygen underwater so as to corrode less, thereby enabling a catalyst with a low platinum loading rate or a thin electrolyte membrane to be used, and thus manufacturing costs can be reduced.
