HIGH POWER DENSITY EVAPORATIVELY COOLED ION EXCHANGE MEMBRANE FUEL CELL

摘要

High Power Density Evaporatively Cooled Proton Exchange Membrane Fuel Cell A method of evaporatively cooling an ion exchange membrane electrolyte fuel cell is disclosed. Liquid water mist 3 is introduced into the anode 6. A desiccant material 8 directs the liquid water mist 3 to the ion exchange membrane 12. Evaporation of a portion of both the product water and the supplied liquid water cools the cell and eliminates the need for a separate cooling chamber, resulting in a cell with high packing density, high current density capability and a large power to weight ratio.
