A fuel cell system including a gas recycling and re-pressurizing assembly. In one embodiment, the fuel cell system includes a fuel cell stack, the stack having an oxygen outlet and an oxygen inlet. The fuel cell system additionally includes two gas/water separator tanks, each of the tanks containing a quantity of water and a quantity of oxygen gas. Both tanks are capable of being fluidly connected to either the oxygen inlet or the oxygen outlet of the fuel cell stack. In addition, the two tanks are connected to one another so that water may be transferred back and forth between the two tanks. The system also includes a pump for transferring water back and forth between the tanks.

Abstract:
In polymer electrolyte membrane (PEM) fuel cells and electrolyzes, attaining and maintaining high membrane conductivity and durability is crucial for performance and efficiency. The use of low equivalent weight (EW) perfluorinated ionomers is one of the few options available to improve membrane conductivity. However, excessive dimensional changes of low EW ionomers upon application of wet/dry or freeze/thaw cycles yield catastrophic losses in membrane integrity. Incorporation of ionomers within porous, dimensionally-stable perforated polymer electrolyte membrane substrates provides improved PEM performance and longevity. The present invention provides novel methods using micromolds to fabricate the perforated polymer electrolyte membrane substrates. These novel methods using micromolds create uniform and well-defined pore structures. In addition, these novel methods using micromolds described herein may be used in batch or continuous processing.
