A Feasibility Study of Using Oxygen Enrichment for Fuel Cell Air Independent Propulsion.
Abstract
It is shown that the output power from a polymer electrolyte membrane (PRM) fuel cell oxygen follows a quadratic relationship with increasing oxygen concentration. Using this information, a potential application of using oxygen enrichment membrane technology for an air breathing fuel cell was investigated. The system chosen was a hypothetical FEM fuel cell powered air independent propulsion system in a conventional diesel electric submarine. A simple model of the system was made using linear programming. The results showed that using existing membrane technology for oxygen enrichment of the incoming air stream, two compressor stages were required whose power requirements were too great for the system. A 30% improvement over existing molecular selectivity in membrane oxygen enrichment technology would allow a single compressor stage, however, 40% of the fuel cell power would still be needed to power the required compressor stage.
