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...

| description | 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.
La présente invention concerne un système de pile à combustible destiné à être utilisé dans un environnement sous-marin tel que celui d'un sous-marin. Ledit système de pile à combustible peut présenter une utilisation de combustible de 99,9 % ou plus par la recirculation d'un combustible même s'il est simplement composé d'un empilement à étage unique, et peut réduire au minimum la commande de séparation gaz-liquide complexe selon un empilement à étages multiples. De plus, le système de pile à combustible n'utilise pas d'oxygène pur sous l'eau de façon à corroder moins, ce qui permet d'utiliser un catalyseur ayant un faible taux de charge de platine ou une membrane d'électrolyte mince, et de réduire ainsi les coûts de fabrication.
본 발명은 잠수함 등의 수중 환경에서 사용되는 연료전지 시스템에 관한 것으로서, 상기 연료전지 시스템은 1단 스택으로 단순하게 구성하더라도 연료의 재순환에 의해 99.9% 이상의 연료 이용률을 나타낼 수 있으며, 다단 스택에 따른 복잡한 기액 분리 제어를 최소화할 수 있다. 또한 상기 연료전지 시스템은 수중에서도 순수 산소를 사용하지 않기 때문에 부식이 적어 백금 담지율이 낮은 촉매나 얇은 전해질막의 사용이 가능하므로 제조 비용을 절감할 수 있다. |
